I tested it myself, and yes, timeout 600 comes back when you log in again (on Xubuntu 13.10). A workaround is to add command "xset s off" as an autostarted application in session settings (provided that resetting to 600 does not happen automatically within session.)
I think PM should override xset setting at least, if you choose Mode > Presentation.
