I do not think that is the right way to represent it.

An "if" == a branch.

I think you can leave off the right branch, since/if nothing happens.

Also, I'm not sure if Branch Manager is an Actor here (i.e. a stick figure). Actors interact with the system. Simply informing an actor is not an interaction.
