How does the electric brake work ?

That's correct. The ESC could not dissipate all the energy on its own (it would overheat very very quickly,) so it dumps the extra energy onto the bus.

The ESC operates like a boost converter when braking.

Take the schematic and substitute the low side mosfets for the switch, the high-side mosfets for the diode, the motor for the inductor, and the battery for the load (on the right side) and that will give you the approximate idea of what's going on.

Thanx!
