Rolling up to a ball, is this a foul shot??

Probably the most under rated skill needed in your safety game by far and it can be very challenging to get it spot on and right.

Now i was watching this coaching video with Barry Stark.....



Go straight to 1:20mins in and Barry plays a shot with his Cue on the cloth right under the Cue ball and just lifts it up vertically to just touch the object ball thus avoiding a dreaded push shot from that range. Now is this a legal shot?? Barry says it is but i reckon it would get called a foul in a lot clubs.

Thoughts??
