EGKB, please don't take this the wrong way, this is friendly advice.
Questioning your instructor on Pprune at an early stage of your training and then declaring after 2 responses to the thread that you are never going to use the landing method taught does not in my view show an appropriate willingness to learn.
You cannot pass a PPL solely from advice on here. You need to develop trust in your instructor. Why not ask him/her to explain on the ground and then demonstrate in the air the reasons for the methods taught?
