How simulated proxy vars replicated to other players?

I know that autonomous proxy client uses ReplicateMoveToServer, i also know that server response to this owning client with ClientAckGoodMove or ClientAdjustPosition, but i dont understand what server does to send move to “Other” players (simulated proxies)?

How simulated proxies receives their Velocity?

Well, i think i found smth: ReplicatedMovement is somehow replicated via OnRep_ReplicatedMovement? possibly via UActorChannel::ReplicateActor.
And also found where exactly Velocity is set: via APawn::PostNetReceiveVelocity.
