That's my take on things as well, though as Andrew pointed out, given those
invalid inputs Excel will produce those wacky outputs.  I verified that on
my Mac a few minutes ago.

I'm inclined to just skip those tests in my Python version, but I can
understand that for backwards compatibility the current module needs to grok
them.
