UMO and UM2 use "software endstops" which means the firmware keeps track of head position and won't go beyond a certain distance. This distance is compiled into the Marlin firmware. The UMO has dual endstops for X and Y axes but one of these endstops is not needed on each axis.

Endstops are to find/set the home position. Therefor you only need one in each dimension. (XYZ or Left,Back,Bottom)
