No, it wasn't. Re-read the original post:
PATH=\~/tmpdir
typeset -p PATH
which produced this output:
declare -x PATH="~/tmpdir"
which proves that ~ was not expanded in the assignment to PATH, but only
in the use of PATH.
I'm strongly in favor of keeping bash's behavior when in bash mode, but
for 'set -o posix', I worry that bash differing from other shells may
mean bash is not compliant with POSIX.
