Yes.

Still, is the tempo 0, or whatever it is supposed to be at the point 
where the transport is holding?

I find it rather useful when the latter is assumed, since it makes 
the fact that audio processing continues a lot more useful. You can 
still jam on and have tempo and beat sync effects roll, as if you 
were looping an empty section in the song. As soon as you start the 
sequencer again, though, beat sync effects will instantly lock to the 
timeline.
