something like that, but not exactly. Lewis starts movement without connection,but probably does so for explaining things...
We would create small opening so aite would attack (i.e. move bokken slightly to the side). Then we would enter (on the line) and make similar movement as shown in vid. We train this go tai, ju tai and ryu tai. The first two emphasize kimusubi (control ma-ai and move backwards) and the latter is irimi (and move forward and deflect in one single action).
So many exercise exist that it is sometimes hard to 'see' what the exercise is for (especially when coming from different perspective)
Thanx for your explanation
