Because it isn't required. On most of those parts the middle pin is internally connected to the heatsink tab, and that one is soldered anyway, for cooling reasons. BTW, the pin isn't cut, the short tab is the way the part is supplied.
Note that the PCB can accommodate both parts with or without the pin.
