This is the way fastpush works according to the documentation and validated by my testing of it:
If code has changed, it also restarts the app.
App reverts to last pushed version when restarted
So this basically reverts the fast-pushed change you just made.
This essentially eliminates any benefit of using fast-push for anything except static files. I tested this with a cf wordpress app and when I modified a php file and did fast-push it restarted the app overwriting my fast-pushed changes with the last cf pushed version.
