How is possible the 18-55 EF-S is sharper ?

That is your word againstthis fact, cheek it out !

The EF-M is sharper at every focal length, isn't ?

The 60D has a strong AA filter:

EDIT: A better comparison.

Well this could be the case with the 60D, but ultimately those shots show EF vs EF and not EF vs EF-M.

It shows that you are building a theory based on flawed evidence. The second one is M vs. 60D and clearly shows that the 60D is softer with the same lens.

Sure but you are assuming that the 60D has a stronger AA filter which could be or not the reason for its softness.
I could shot a rez chart with EF-M 22 vs EF 40mm but any difference could also be attributed to focal length. Longer FL tend to be easier to get sharp than wide. The EF-S 24mm would be a more reasonable comparison but I don't own one.
