What is a known potential failure scenario if the floor flange sits too low relative to the finished floor?

Answer

The wax may be completely squeezed out the sides and up the interior horn due to lack of material remaining for a proper seal.

When the flange is recessed too far below the finish surface, there might not be enough wax material left to achieve the necessary compression without the wax being forced entirely out of the joint.
