All he said was that when faced with fast balls (which seldom happens in rec tennis), have a short takeback and block the ball and send it back with the pace of the sender. People have said this about service returns and volleys for a long long time.
In rec play, the challenge is usually the opposite. It is about how to put away slow balls and hit to where the opponent isn't.
The other problem with OP is that it claims racket takeback is not racket preparation. A short takeback is ALSO a preparation, sometimes reflexive and sometimes acquired through experience with faster serves.
The reason you don't feel the takeback is because you're unconsciously competent; it happens automatically without thought. Great if you have that skill. But it doesn't help someone who doesn't have the skill. In order to get to that level, you have to go through many reps where you are explicitly thinking about it until it becomes cemented firmly.
I *think* this is what
@mcs1970 was driving at.
Guys, look
It's fact that there's a huge gap btw written words in TT and performing tennis actions. It could be that a perfectly written instruction possibly leads to a completely crappy tennis action, and vice versa a poorly written phrase leads to an eventual break through tennis action.
With that in mind, I rather not go down the rabbit hole of nitpicking apart anything or scrutinizing anything, and my impression is that's what you guys are doing! Well, whatever, if that floats your boat.
Another thing, maybe my foundation is already there, and all Thomas did was trigger an idea that I long forgot.
I don't necessarily know precisely what he means by "... instead think racket prepartion first and always" but it's good enough for own take-away. Another coach in this place also wrote the phrase "protect your contact point at all cost" -- whatever he means exactly but it rings true with me.
