Here's a vid from David Valadez on YouTube. Ignore the content, and watch from about 1:29-1:31 and 1:50-1:53. The arm is completely outside his center. *IF* that's a "standard" technique or way of doing things, IMO, it's a bad technique. You lose power, control, and focus on uke in that instance.
Mark, you are right. That way sucks. You really have no power and you end up using a lot of arm to regain the centerline, which usually doesn't work in a fight.
