Some of those two speed systems employ techniques to lower that output of the scroll compressors even though they are running at full RPM. One method I remember is the medium pressure port.

The low speed option does increase efficiency since it lowers the number of cycles but more importantly is the increase in comfort since there is less temperature swings.
