Trackball programming

I tried to understand the trackball schematics. It appears that right/left are changing at exactly the same time. So it is not a typical signal with the phase telling which way the ball rotates.

 

It also has a monostable gate that sets both directions to zero when the movement stops.

 

So my interpretation is that you can only sense the direction by looking at which pin the pulse train starts at (right or left). After that you can sense the speed by looking how frequently the pulses arrive.

 

Am I correct in my interpretation?
