The two main cases I see are:
a) future proofing
One day, perl may move to another location than /usr/bin/perl (yes, I know it's
unlikely). On that day, you can change one macro (by modifying %{__perl}) or
change all your spec files. I know which one I prefer.
b) brokeness proofing
While simple 'perl' works in a mock/koji context, our sources rpms got rebuilt
in other build-systems, not all of them as solid as mock/koji. I can't
guarantee that plain 'perl' will work the same way that %{__perl} does in those
build-systems.
