Hey now.
The purple arrow direction is achieved by commanding higher PW at lower injection pressure. It hasn't got a whole lot of anything to do with RPM (except if you're looking at the MFD......but even that can be high at a low RPM or low at a high RPM; it all depends on load).
More to come...WITH PICS!!
