No, that's not correct.
He's talking about First Focal Plane scopes. These scopes have the reticles etched onto the first focal plane. This allows the reticle to increase in size in proportion to the magnification. This simplifies range finding, as one doesn't have to do the extra step of dividing the measurements in half (I may be off, I haven't practiced MOA reticle range estimation in a while, it might be multiplying) by 2 if you double the magnification power.
If your scope is made correctly the zero shouldn't change with magnification.
