An account can only exist in one place at a time, but it's almost zero effort to transfer it back and forth, you just need to use the SNS to tie your account to twitter or facebook.

As for what nubee thinks about it, I don't know but I've transferred my account back and forth several dozen times. And yes, it ends up creating a new account on the previous device each time.
