Does random mode on the 200 series take advantage of the alternating gyre?

If the controller is set to random mode, will 'alternating gyre' be one of the modes it incorporates into the random flow pattern ... or is limited to just random pulses in one direction?

In other words, if I set to random mode, will all 4 other modes - constant speed, pulsing, gradual pulsing, AND alternating gyre - be randomly implemented ... or will it be limited to a random implementation of just constant speed, pulsing, and gradual pulsing?
