I think that the check is for the condition that "one can both read and
write", before proceeding. The IsBad logic forces a somewhat reversed
logical structure, i.e. "if not both read and write, fail", which is
coder-optimised to "if not write, fail", since if we can't read we also
can't write.
Read-only is failure, as is a NULL, or any other bad pointer.
Assuming I've understood the previous discussions correctly...
