Yes, your logic and approach is correct.

Assume you have only one primary track then, obviously, every track you'll ever encounter in your simulation is either the primary or daughters of this one primary track. If that's not the case, let's say you have two primary particles, then the situation is more complicated because you now also need to investigate for every track who the original parent was of the two possible.
