Yes that is quite different. No antidive on the X, so no line to the rear brake. Still its is excellent brakes and I hear the F6Bs are also great, prob even better. It is my understanding that a "high side" is when you lock up the rear brake and the back of the bike starts coming around on you, you get off the rear brake while already going somewhat side ways. That result is the back tire stops sliding and the bike tosses you high to make a less than soft landing. Very common. The rear brake cannot be locked up with the system on my VTX. I call it Honda making the bike stupid proof because you cannot "high side" which the major cause of is people being scared of the front brake.
