Right. That command is equivalent to:
373af0c 590dfe2 --not 373af0c^ 590dfe2^
So the limiting for one range you're interested in ends up marking part
of the other as uninteresting, and that's by design. This topic came up
recently, and I think the general consensus is that it would be cool to
be able to do totally independent ranges, but that would be backwards
incompatible with the current behavior.
In the general case, you can emulate this with:
{ git log 373af0c^..373af0c
git log 590dfe2^..590dfe2
} | $PAGER
which is of course slightly more annoying to type. If you're just
interested in _single_ commits, though, you can just give the commits
and turn off walking:
git log --no-walk 373af0c 590dfe2

I think you could even drop the rev-lists in this case, since he just
wants a single commit. However, cat-file lacks the niceties of "log",
like fancy --pretty formatting and automatic diffing against parents.
