Trap
The meeting spot was arranged, and Sam needs to go there along with his team the next day.
Sam sent the bird puppets there and let the team rest and prepare for the next day.
The location of the meeting is the forest. Sam looked at the screen to make sure that the tundra sect is not doing anything fishy.
While Sam is doing this, the sect had another meeting. It is not about how to deal with Sam's matter, rather it is to discuss the possibilities on how their location might have been revealed and how they should overcome it.
For then, being hidden is a necessity and there shouldn't be any problems regarding that matter.
As for why they are leisurely chatting about this instead of thinking of ways to deal with Sam, in their opinion, Sam is already done for.
