Based on the prior holes, the fitter first put the screws in a centered position, then moved the blade. So he did what he did on purpose.
The lowest level hockey techs wouldn't know how to do that, or why it might need to be done - so the guy knows something about figure skate mounting. He might well be competent.
That's part of why I suggested getting the tech and coach to talk to each other - it is conceivable that what he did makes sense for your daughter's body.
I can't tell from the pictures whether he filled the old holes with something - if he didn't, moving the blade back to center would be very easy for you to do - but you should get that discussion first.
I'm also a little unsure of whether he warped the blade in the process of mounting it, because he may only have moved the back screws. Could you put straight edges along the sides (near the bottom of the blades, which is on top in your inverted photo positions), to see whether they are straight? (In case you got parabolic blades, do it on both sides - parabolics [which are ground thinner in the center of the length] might look warped on both sides, at least in the bottom-most area where the chrome has been ground off, which is where the parabolic grind is probably done, but would be symmetric.) If there is a detectable air gap (use no pressure to force it straight), and you don't have symmetric air gaps on both sides, it is warped. (If the gap is a sizeable fraction of a mm, that would be very bad - some skate techs won't even try to un-warp a mm or more of warp, but would send the blades back to the manufacturer, because that is large enough that the blade might break if they try to de-warp it.)
I used to have seriously warped blades (I would never use that skate tech again!). They got quite hot while skating from all the extra friction, and they were quite slow as well. In addition, they were harder to sharpen right - some types of machine sharpening equipment would create uneven edges, in which the left-right edge height differences would vary along the blade. (Specifically, one edge might be longer in the center of the length, the other edge might be longer at the ends.)
One very crude way to check for uneven edges without fancy equipment is to lay Popsicle sticks across the edges, on different parts of the blade. They should look at right angles to the sides of the blade (hard to judge exactly, I know), and if you lay a pair of Popsicle sticks across different parts of the blade, you should be able to site along them to check that the two sticks are parallel. While they aren't precision measuring tools, in part because the right angles are hard to judge, you can buy a bunch of Popsicle (or other brand) at a dollar store, so they are cheap compared to the cost of her new boots and blades. Just make sure they aren't warped either, using that straight edge.
I'm not saying he warped the blade (or that it came warped) - just suggesting you check. While you are at it, check the left blade too.
Because the tails are a bit further forward (a combination of mount position and blade length) than is typical, it is also possible the tail may tend to drag a bit. That would slow her down too - but I'm not sure if the shortness is great enough to matter.
Whether the blades are really too short, if mounted right, depends a lot on her feet. In particular, if her feet are substantially shorter than the outsole (something that sometimes happens on stock boots, especially if her feet are a bit too wide anywhere to fit the boot maker's foot shape assumptions), she might skate better on blades that are a bit short. Though, to take advantage of that, I would think he would have mounted the blades further back, both so the back corners don't drag, and so it is easier to roll forward to the toe picks.
Anyway, good luck!
