I think that almost all of the successful shots with inside follow for a ball frozen to the cushion have the cue ball first contacting the cushion. Considering throw, the cue ball must be in the cushion when it contacts the object ball or the ball will be thrown into the cushion and miss.Y ... I assume that you hit the OB first. (you can never hit the OB and the cushion at the same time, you either hit the one or the other first) If you hit the cushion first, the CB changes path completely. It will get a ton of spin, and you may scratch at the opposite corner pocket, or even hit the long rail.
Most people don't realize how long the cue ball is in the cushion and how deep it sometimes sinks. There are trick/fancy shots that illustrate this.
