Replication Question in Third Person Character

Before this, I have learned some thing about it.In UE4 Editor, run as client for two,then there will be two Characters.It is easy to understand,Two clients join serve and serve spawn Actors it serve map,Then replicate to these client.So I try to uncheck the replicate in Character BP.For this,I think the Actors on serve will not replicate to clients.But it still work,I do not know why,I was very confused.So Would someone tell me why?Thank you very much.

The reason being that Pawns are forced to replicate at runtime whenever they are possessed. So that’s normal Unreal behavior that you could change if you override APawn::PossessedBy().
