If you modify the buffer it doesn't revert.  Only unmodified buffers
will be replaced with the contents of disk files if those change.  I use
this for org-mode files and git - save all buffers, commit changes, push
to other machine, work there, commit, fetch back to first machine, and
all my org-files automatically update without me doing anything special.

Try it on a test file or two where you modify the buffer first and don't
save then change the file on disk with another editor and see how it
works.  I haven't had any problems with it yet.

I auto-save my org-mode files every hour in my workstation emacs and I
tend to just leave my workstation emacs running forever.

,----[ .emacs ]
| (run-at-time "00:59" 3600 'org-save-all-org-buffers)
`----

I use this mainly for my cron job that automatically creates git commits
on the hour.

This has a nice side effect that I can just leave the house with my
Android phone, (the files save at 59 minutes past the hour), then I can
SSH in to my workstation, fire up another emacs process on the phone and
edit my org files and save.  They auto-revert on my workstation and
everything Just Works(tm).
