imagine a ball as a circle where 12 o'clock is toward the opposite court, straight toward the center mark. To hit inside out FH (for righthanded player) you need to hit the ball anywhere between 6 and 9 o'clock. If you pull the racket inwards, the plane of the racket face is moving from general area of 3 o'clock to 9 o'clock (meaning right to left).
Could you explain how the plane (a racket) can touch a round object (a ball) between 6 and 9 while that plane is moving from right to left?
This is not exactly the point being discussed, which is an even more absurd claim, but it is a nice question. I would say that inward motion is not just right to left - it has to be a motion towards the body at contact time. I think some people found it too literal and want to think of right to left as inward also, instead of well, simply right to left!
In any case, the way you have framed it is what some people appear to be thinking, so let us go with that.
The answer is, of course, that it is not possible. Pro videos show the racket face both almost perpendicular to the ground, and perpendicular to the intended target direction, at contact. The racket continues in this path for a while before turning over.
