Clarification on fighting technicals

[Scrapper1]

We've had discussions about whether certain technical fouls offset during a fight. For example, if A6, A7 and B6 come off the benches and only observe, but B7 leaves the bench and participates. In this case, there's an uneven number of non-participants and an uneven number of participants. Do all the technicals offset? Or do they only offset within each category.

Not sure why I never saw this before, but 10.4.5 Situation A in the new casebook addresses it almost exactly, stating that no free throws are awarded and play is resumed at the POI. This is marked with an asterisk, to indicate that it's a new ruling, but there's an almost identical ruling in last year's book. It's 10.4.5 Situation E.
