Note: I've not worked work that specific looper but that should generic (and works on the 505).
Not if you're in free length mode for each loop: in that case any finished loop will restart when reaching its end and it's fairly impossible to keep two loops synchronized (this is usually the expected effect when not synchronizing loop). If you asked for start synchronisation, it might restart with the first, it really depends on the mode and the looper.
If you want the second loop to wait for the restart of the first one, you need to synchronise them. Actually, the behaviour you describe can be obtained with the second loop quantised on three timrs the length of first one, with the last part being silent. This can be achieved or by quantising the loop length to the first loop, or by linking start and stop. Both ways will allow you to have loops of lengths being a multiple of the initial loop, even if part of them is silent.
Maybe you can explain exactly what you want to achieve, from the question it's not clear (at least for me) if what your describe if a wanted or unwanted behaviour.
