It's not our decision which interpretation of POSIX is correct; we would
have to request an official clarification.  But I just noticed that the
general description of ENOTDIR states the Linux interpretation:

[ENOTDIR]
        Not a directory. A component of the specified pathname exists,
        but it is not a directory, when a directory was expected.

I have filed a request to clarify the meaning of ENOTDIR for all
syscalls:

In any event, it is your (Wayne's) decision whether it's a goal for
rsync to work on all POSIX-conforming systems, but if you are deciding
"no", please be clear.
