I will simply say that in many other circumstances I think it is detrimental to think in terms of extending or flexing in order to turn and/or during the course of a turn.
And there is the crux of the argument (or possibly the agreement).
If I'm running a GS course or a fast groomer and want to absorb a roller to avoid air time, I'm all about contracting, flexing, and extending. Since my current favorite on the WC tour is VonGruenigen (oldest guy to win a WC event), let's use him as an example. His legs look like a spider's, always working to adjust to terrain while keeping his upper body stable and his skis on the ground. Actively flexing the legs to absorb terrain is not only a good idea, it's the law.
Now if we're thinking of flexing and extending to initiate a turn, I would say that's a very wrong approach. I would believe that would lead to a pushing mindset instead of an edging one. By actively extending, you are actually pushing your legs away from your CM, which can lead to banking. Do your legs extend during a turn? Absolutely. But to focus on that aspect as part of the basic components of a turn does more harm (in my opinion) than good.
In other words, I think you're all right.
