Why? Or should we/they change logic that completed out of order?

yes out of sequence logic and be viewed in the P6 log report.

you can have logic pushing through an activity ie.

Activity A B and C all sequential 

Activity A is in progress 

Activity B is completed 

Activity C has not started

Since activity A is not complete the earliest that activity C can begin is when activtiy A is done. Even though activity A is not tied to activity C it is still honoring the retained logic and passes thru activity B to activity C
