The short answer from my experiment is "yes". The layer of peat moss
was still wet this morning (not moist but actually holding free water).
I watered last night and included the experiment box. Holding water
overnight in one layer is not free draining.

Whether the wet layer will act as an artificial "bottom of the pot" is
open to conjecture but the wet layer can't be good for the roots.

I too have always noticed that the bottom of pots are filled with roots
first.

So in regards to perched water tables and layered soils, is there a
possibility that layered soils will create a moist layer in the middle
of the pot, and thus an artificial "bottom of the pot" thereby filling
that layer with roots first.
thanks,
