Even if your workpiece is 'square', the technique explains how to minimize the effect of any 'squareness' tolerance.
In other words, by using the technique, you conserve workpiece precision instead of giving some away due to common end stop placement (at the vise jaw).

Why it is important to position a stop in the centre of a datum edge or face.
Every little helps when it comes to accuracy. In the video demonstration the datum edge on the part has a severe compound taper which can still be cancelled out with the stop in the correct position. Always having the stop in the centre of the datum face is good practice when setting the part...
