You are right when you say that detachment of bodies is not necessary. Just an 
anchor reset.

But if you move two bodies that are linked, and the joint does not match 
exactly at that moment, then just setting the anchor again will introduce a 
drift in the joints after successive translations. That's the reason for 
previously setting the bodies in a way that matches the joints, and then 
reset the anchor.
