There are lots of positions where the first object ball is sitting just barely to the side of the path the cue ball would take if banked directly to the second object ball. In those situations, if you just barely skim the first object ball, the cue ball continues on its banking path. Sometimes it's inside english, as with the Jeanette Lee shot shown, and sometimes it outside english, but usually the shot wants running english.
From the number of overly-thin hits on the video, I'm wondering whether Jeanette might not need to try a carom cue.
