I agree that it would have been a nice clarification, but it's not common to list the things something is not. Usually definitions are limited to positive statements. This might be on account of the list what stuff is not being a bit long.
Dazed has the same consequence. And a figurine's activity level is close to being dazed: it can't take out-of-turn actions, and is very limited on its own turn.
Okay if you cant flank when Dazed, that adds some credence to figurines not being able to flank.
I just wish there was a clear ruling, but doesnt seem to be.
Counter to the daze argument, is that in theory the figurine can do 3 actions if you so command it.
