The diodes are reversed between ground and the rail.  If you reverse the
supply they will short.

The Neutron Sound version of this is a little SMT diode bridge.  A tiny bit
more expensive, but less PCB real estate.

Whether the diode drop on the rails is significant or not depends on who
you talk to :)  Personally I like it.
