ooookaaayyyy Thats a whole 'nuther kettle of fish!!
I thought he was adjusting for offset, as Marc described. I wont muddy the issue further then.
I think what Marc calls a drawtube I call a sighttube, and if this is the case then its a long tube with a cross-wires at the end which you use to get the secondary in the right place before you use the cheshire.
I know its going to do your head in for a while but persevere, it will make sense eventually and seem straightforward and simple. And if you're going to continue with just a laser you will need to get to grips with the offest issue for best results.
