Pickoff at first

[TwoBits]

Had a team do this several times today:

USSSA played under OBR on a 70' diamond. F3 played about 2 feet in front of the line between first and second and 6 feet toward second. They would do a pickoff play where F3 would move toward the bag at the same time F1 would throw the ball over using a jump turn. On occasion, F3 would catch the ball 2 or 3 feet in front of the bag and try to do a swipe tag. The throw was directly in line with the bag, but since F3 cut it off, it never actually got to the bag.

There have been numerous discussions here that a throw not directly to first base while on the rubber or using a jump turn is a balk. Since this throw isn't getting to the bag, is it still a balk?
