On a Mac, shift with caps-lock on doesn't toggle to lower-case, so they would need to store a fourth version for this to work.

Overall it's a clever UX hack, though I worry they came to it by observing invalid password attempts which seems slightly outside of appropriate, although it doesn't particularly bother me in this case.
That would make all passwords essentially case-insensitive (all uppercase would work) and that would make it much easier to brute force than the inverted version.
