How does the Flare controller work?

Just wondering how the Fixed wing flare control works. I notice that it has a Flare max and a Flare minimum angle, yet when my plane lands it only holds flare minimum. It lands very well, I’m just wondering how it actually works.

The code is here if you’re curious - https://github.com/PX4/Firmware/blob/master/src/modules/fw_pos_control_l1/fw_pos_control_l1_main.cpp#L1605

Flare max and min are pitch limits for TECS.
