Agreed. SAWS is useless if you cannot aim center-ball shots accurately and stroke straight.
I'm not a certified instructor and don't give lessons. But I have shown a few people who never held a cue in their hands
to do what you posted above and totally agree with the aiming center-ball shots accurately and stroking straight. No offset, no spin/English, and not even an OB.
The first thing I did was teach them how to hold the cue with either an open or closed bridge and then how to stand behind the ball and position their head and eyes to get it to go where the target was. The target was the pockets and the only ball hit
was the CB close to a pocket in the beginning and then further away until the entire width and length of the table was used.
It wasn't exactly an easy task for most of them, or me to have the keep doing it repeatedly and still miss. Even with that, their stroke was disjointed and awkward.
Eventually if they stuck with it for a number of days, we included an OB. And then the fun, or lack thereof, started all over again.
We don't remember those days for ourselves now, but pool isn't easy. Adding tip offsets to shots for spin too early is a kiss of death for newbies and unskilled players. Even skilled players can blow shots from the use of spin and miscalculations.
