I'm confused by this comment. Does this mean that you think KPM is on the right track (perhaps due to Alan Orr) ...or not?
No. Still quite far.
Excluding and including punches, as I've seen in some lineages, are a "bridging" idea where you attempt to occupy the line and "wedge" the opponent out while you punch. Depending on how you contact the opponent's arm you'll need to raise or sink your arm in order to keep them out. This is totally dependent on contact and is puppetry, only, the opponent is the master and you are at their mercy.
An example is in the video below (only one I can find). You'll see as he attempts to wedge the opponent out he is forced to raise his arm up, so much so that he's "punching" to the top of the guy's forehead with his elbow popped way up, or even fanning his elbow in order keep the opponent out. The focus is not actually on delivering a decisive blow, but wrestling for the line. This is the result of missing strategy elements, starting from
man/wu misconceptions, and an obsession with "occupying center" at the expense of solid punches with body mass behind them.
As for a cutting punch, referring to the "whipping" punch Alan does, a sweep to the outside is needed to then cut back in toward the opponent. Again, this required detour to the outside in order to cut back in is a workaround for missing elements of strategy.
Can this whipping punch work? Yes, it has been proven in the ring, so props there, but it is indirect, gap-filled Wing Chun. There is nothing necessarily wrong with indirect and inefficient methods, since most MAs are like that, but they aren't functioning according to VT principles which are designed to make fighting easier, not more complicated and harder than it already is.
