Baseboard moldings always have a cutout on the back side. What is its
purpose?

Is it there to relieve cupping stresses?
Or maybe to just allow for flat placement over imperfections in the wall?
Anyone know the actually reason for this?

I'm not asking for guesses or speculation.
I'm sure someone out there actually knows this info.
