The issue is a) communicating that to users. and b) Even if you know that, if your phone breaks and you revert to an older phone or a cheap android to tide you over... you didn't get a chance to sign out.
I'd say the problem is they're keeping you signed in for too long. If my phone doesn't check in for 24 hours, shouldn't it un-register me at least until I next check in?
