Could someone please elaborate on this?

My "visual" brain can't quite visualize this.  Do they mean an intersection
like this?  (This of course *must* be viewed with a fixed pitch font.)  As
I understand this, they mean the legs of the intersecting angles are
supposed to be equal in length.  So if you *didn't* want to use a CV joint,
you'd turn the axle so the pinon points markedly upwards to form the equal
angles.  This would of course result in needing to turn the axle ends to
correct caster.
