I think you are correct.

In most cases Ant's behavior probably is exactly what is intended by
many people.  You don't want to lose your real work when removing
backups recursively (deleting the directories that don't contain any
backups because no file matched the include pattern).

When deciding whether a directory is empty, Ant asks the OS and
doesn't only consult its internal list of files that matched the
include pattern(s).

I'll update the manual.
