Hi,
It is expected. Autosaves and backups are two differents things (I
thought you were talking about backups). Backups is about keeping a
copy(ies) of previous version of your file *at saving time* and
autosaves is about keeping the modifications you've made *until you
save* them. You could read for more details in the info Emacs manual.

You could do:
M-: (normal-backup-enable-predicate (buffer-file-name))
and
M-: (file-remote-p (buffer-file-name))
But it won't help you for autosaves ;-). You should read the
corresponding section in the Emacs manual.
