Yeah, except it's not the entire story and because of it's over simplification ends up being basically wrong.
"Figure 3 (a) shows that the optimal braking maneuver (dash line), which uses also the rear brake, is able to reach the
ellipse of adherence, except when stoppie condition occurs. There is a net gain in the maneuver performance which is
quantified by the highlighted yellow area in the Figure. However, the optimal braking strategy acts to the tire limits and
including the fact that the load torque of the engine in many cases is high enough to lock the rear wheel, only few racing
riders are able to put into practice this optimum braking strategy. The same cannot be said for acceleration maneuvers
since traction force is only available at the rear wheel."
Now make sure you properly read figure 3a because for straight up and down braking it shows stoppies occurring meaning there is no gain from rear brake usage.
