Yeah, you can push and pull something and you can also use the term to describe the motion. You clearly said pushing/pulling MOTION in your post that started the debate and when reffering to the Motion, where the load is doesnt matter. What matters is 1) Where the force is being applied (the grip) and two wether the force is moving toward or away from you.
The backswing is a pushing motion no matter where the load is.
My thinking, as in my original post, is that I agree with you & Fran. I added a part about pronation & supination.
Since we are biomechanical beings & not precisely built robotic machines, our arms hang down in their natural manner, yet we are individuals & the angle of each individual's hand to the body may be slightly different. Depending on how we connect to the cue could effect what we 'feel' we are doing when.
CJ does not particularly like the term but with the hand rather on top of the cue, to me, there is a sense of making a 'stabbing' motion. A double pointed spear sort of placed on the bottom of the hand we would first be stabbing behind us. Then as the motion goes forward we would be stabbing out in front. I only used the double points to differentiate for direction purposes with the hand between with no 'load' but instead a purpose of direction.
I doubt that anyone using a full pendulum swing would easily relate to what I just said.
Take out the spear pointing back & then just picture a spear with the point out in front like the tip. We pull the spear back to get distance from which to thrust the spear forward. That goes against what I said earlier in my original post about pushing back away from our body.
It's all about relativity as in Einstein's Theory of Relativity. Well...not exactly but the point is that the English language is a bit lacking at times.
If I picked up a spear & thrust it into an animal skin hanging to dry & then gave it to you & said, "UGGG" & made a hand motion, you would know what I meant.
To me, there is much that exists that the motion that causes the cue to move like a piston can be associated. I, for one, & there obviously are others, don't easily see much that a pendulum swing can truly be associated as it relates to moving a straight implement 'straight'.
Perhaps, take a spear or a sword & swing the arm back & then thrust it, the sword, spear, or cue stick forward. But that would pivot at the shoulder & that wrist sort of changes things as it tries yo keep the point from going to the ground so the spear, sword, or cue stick can be thrust forward & not swung up to the sky on the forward thrusting motion.
Would it be fair to describe a stroke that moves the implement in a thrusting or piston movement as an athletic motion & the pendulum swing as a mentally contrived nonathletic mechanical motion?
I know one seems to sound better but that's not the point, as I said the English language is sometimes lacking.
This post started out to you & then went rhetorical. Sorry.
Also it just some my thoughts & naturally could only be considered as my opinions.
Best 2 You & All,

PS I believe & think that how we connect to the cue should dictate how we move the cue stick so as to not be fighting against one another. Depending on how we connect to the cue & move it, perhaps there should be an associated turning or twisting of the cue, I know I have seen some rather good players that do just that. They have a twist to their delivery of the cue, but as I said that may be more of an individual thing given the angle the arm naturally hangs.
