I believe the reason is that M-x revert-buffer will happily throw away
any minor-mode you currently have (which is OK since you asked explicitly
to revert the buffer), while auto-revert is being a bit more conservative
and tries to only revert the buffer's content without changing the
major/minor modes.

So I'd say it's a bug in auto-revert.  You can try the patch below.
