Those don't even look like the same blades. It looked like he destroyed one blade and found an old one in the trash and replaced it.
It's a little hard to tell from the picture, but if one blade is really thinner than the other, Agnes might be right. Removing a lot of metal is easy for an incompetent sharpener to do, but changing the thickness using a standard sharpening machine would require a very non-standard usage of that machine.
Can you see whether both blades are still labelled "MK Phantom", and both still have the fancy MK engraving?
However, if I remember right, MK Phantoms might have a dovetail shape (i.e., they are thicker at the bottom), so that removing metal at the bottom does change the thickness of what is in contact with the ice. If you have fancy calipers or a micrometer, you could use them to find out if the thickness is different at the chrome relief line (the line where the blade changes color, and below which becomes abruptly a little thinner), measuring at the same point along the blade, like under one of the stanchions. Regardless, the characteristics would change completely, and people typically throw dovetail blades out after relatively short lifetimes.
OTOH, maybe I am thinking of the "Phantom Special", which is different blade.
It is also quite possible that after sharpening by a drunken chimpanzee*, the bottom sides of your blades may not be symmetrical, and have very different side cutting on the two sides. They might also have a wavy thickness pattern at the bottom, which gets thin and thick in a complex pattern. You might see that by placing a straight edge against the bottom sides, and looking at the gaps.
I don't think your blades can be rescued, if you care much about how you skate. If you are done with them, perhaps the sharpener you trust will keep them, to show other customers why they should stay with him or her. A lot of sharpeners love to do that.
Personally, I would be reluctant to trust high end blades with fancy side cutting to anyone but an extremely well-praised sharpener. Perhaps, in the future, you will too? Such blades are very difficult to deal with well, which is one of the reasons a lot of people use simpler shaped blades.
