Hmm - one could suspect that the POSIX people did just try
to document the status quo.
A logical reason could be that the "&&" explicitely tests
for the exit status, and the intent is that "-e" does not
exit if the exit status is tested for.

Yes it does. To quote xcu_chap02:
An AND-OR list is a sequence of one or more pipelines separated
by the operators "&&" and "||" .

Well, the documentation is poor, but the idea that
an explicit test for the exit status inhibits the
automatic exit makes most sense for me.
