If the filament gets too hot from the stepper, build plate, heat rising from the hot end, it can get softer and become more prone to bending below the extruder gear rather than getting pushed into the hot end.

This + also shears more easily at the extruder gear,  and can swell in the cold zone. But mostly what Ian said.

Seems like it cools the filament before it gets in the extruder and is melted.
