OK, thanks! That makes sense. I guess I just didn't understand the statement:

If you noticed braking can be done with only one side, while recuperating involved both.

My confusion stems from the diode aspect. I know the diode is built into the FETs. So, if the FET simply shorts the phases, how can you eliminate the v drop of the diodes?
