The printer uses Kelvin Coupling, as demonstrated here (credit to Wikipedia)

A total of six contact points is required for kinematic coupling. The bed mount emulates that using magnets.

Point 1 (technically infinite points, but it is to emulate the three point inverted pyramid):

Point 2 (2 points):

Point 3 (1 point):
