Land climbs to 0 altitude when landing on lower plane

I’m doing a land command in a mission to a lower than launch surface.
The quad climbs to 0 Altitude before descending and landing.

Launching at height 0
Moving to a way point at -20 meters below launch.
Issuing land command, the copter climbs to 0 and then starts descending to land.

Is this behavior configurable?
