Stalling on engages

Here's what the raid policy states

So the whole point of this is to prevent stall tanking right? What about the new escalation of tactics where the two "trackers' are face tracking characters armed with discs and soulfires?

Inny popped, TMO's two monks popped up, 1 took the DT, the other stalled long enough with whirlwind+soulfires until the cavalry arrived and burnt the god down. Wouldn't this be a violation or at least a bending of the rules? The whole point is this is supposed to be a race and it's not really a race with these escalation of tactics.

Would like a staff response please.
