If Colin stops Hoppa the OZ title is his even tho the fight is not in OZ. And if outpointed over 10 rounds the title will become vacant.
Likewise if Lawrie stops Daniel, who agreed to meet @ 90.7 limit., which I didn't think they would. If Dan is outpointd, the title is safe as the fight over 6 rounds.

I wonder if respective teams are aware of this?

Yes

Ammann's trainer/manager Peter Hallett wasn't, because he thought Tauasa was now Samoa resident.
But he ain't concerned. His words; "If Lawrie is good enough, he can have it"

What i find interesting is that at this stage in their careers Ammann and Lawrence are fighting a 6 rounder.

That is a ridiculous situation...
