This is awesome. You have become a two-way pickslanting ninja. Complimenti!
Looks like you put this up a while back but I’m just seeing it now. But this is a great example of several things we’ve been talking about recently, in our recent crosspick broadcasts, and on that very long thread about how the term “pickslanting” should be used.
Short story, you are supinated all the time here. Yes, there is forearm involvement, but like Andy Wood, it’s only taking you from more supinated to less supinated and back again. If you ignore the arm movement for a moment and just look at what the wrist is actually doing, you’ll notice the 9:00 and 2:00 movements for “dwps” and “uwps”, respectively, which we’ve been learning about. The arm just occasionally re-orients the whole setup slightly. We can ask why or even if that needs to happen. But it’s not changing the fundamental nature of the motions.
So we’ve come a little bit full circle in our understanding of what pickslanting really is and how many players actually do it. It is very often a wrist thing, and in those scenarios, the arm is just there to provide a slight orientation assist - for reasons we can speculate about. But the flip-flopping motion paths appear very often to come from the wrist, and they don’t depend on the “slant” of the pick, per se.
There are clips in the Pickslanting Primer where the actual arm involvement drops to almost nothing and still the pick escapes. You can take a look at this clip, for example:

…and you will see that the arm never approaches anywhere near actual pronation with respect to the strings. It’s just varyingly supinated. You can take a look at the third note, the downstroke on the top string, and note very clearly the 2:00-style movement that I’m using to get over the string. It’s a little embarrassing that as recently as a year or two ago, we were filming this stuff and not really appreciating what was actually happening.
You have mentioned that your approach can sometimes feel “subtle”, or “neutral”, but that is not really what’s happening. We have been overly focused on the appearance of forearm rotation in determining when “2wps” is happening. Instead, what matters are the motion paths. If you use different escape motions depending on the string change, that is really what the “two-way” in “two-way pickslanting” is all about. When you think things feel or look “neutral” I’m guessing it’s because you don’t feel arm involvement, and that’s how you interpret it. But that’s just what wrist movement feels like.
