It's another check one of the gizmos is working well.

I think its a good policy, Tony. It is one more anomaly to catch your eye
if you should happen to be on the wrong strip of asphalt. It also sets you
up for a return, if required, as most times landings and departures are on
the same runway. I always used to setup the approach on every departure so
if we had to return, the PNF could just flip a knob and we'd be set up for
the approach.
