From the rules at bkgm.com: "You are not allowed to block all six points in your starting table."

Does this apply in the middle of a move?
If I for instance occupy all the points in the starting quadrant except the 19-point and have a bunch of extra checkers on the 24 point, then roll 55. Am I allowed to move 24-14, 24-14, even though the moved checkers will temporarily complete the prime on their way?
