New racing technique

The new comet of the World Cup, Johannes Klaebo has invented a new style that's really worked well for him. It's a kind of running or jumping stride / herringbone.

Notice how high he lifts the back ski. They say this way allows for max weight over the grip zone, and frequency can be increased as well. Looks both funny and cool at the same time, what do you think?

Seems he is also working on new and improved techniques in the other styles as well.

Seems logical to me. Most of us are probably runners anyhow so why not run on the skis?

Yes, it is a both effective and funny looking technique. A diagonal stride without gliding. Cross-country skiing was originally called "skidlöpning" ("ski running") in Swedish, so this new(?) technique is back to the roots.

Added another video to show it's used for herringbone and not just striding.

When you look at the original video, other skiers are doing something somewhat similar, except they don't lift the skis as much off the ground as Johannes Klaebo.
Let's say track runner A is running with his usual gait, and runner B running a bit faster using the so-called "skipping" (high knees)
Does it mean that skipping is a superior running technique that makes runner B run faster?
Of course not. In skipping (same as in Klaebo technique) you lift your legs off the ground more than necessary for the forward propulsion.
This means wasted energy.
Runner B and Klaebo are running/skiing faster because they are (at least at that specific moment) noticeably fitter/stronger than their competition.

No, pundits and trainers say this way is actually superior because the pressure on the grip zone is increased for better grip, and the angles of the leg enables him to start the push earlier.

Here is a pic from a video where the technique is being analyzed and compared to Emil Jonsson who is known for his good herringbone:

Well, let's wait and see then. This technique will likely be analyzed, and most importantly MEASURED during the off season.
If it is superior to the current technique, we may see a lot of competitors adopting it for the 2017/18 races, otherwise, it will be just a flash in the pan.

At the core, maybe one can see it like running without skis up a hill normally compared to dragging the feet low and waddling, herringbone style. Same for striding, but here with a gliding move.

Maybe it's more tiring like you say, but they say faster. But then double poling has replaced a lot of double pole kick striding areas from before, despite it being more tiring, showing that it's the speed of the technique which counts.

I doubt it will be a measure of its success if all start using it next season, as it's pretty specialized and against the grain of most, one would need a bigger time scale than that to say one way or the other.

This is an interesting point. The new technique may indeed be faster, but at what cost?
It's not clear if double-pole is indeed more tiring than kick double-pole, and if so, the difference is small.
Hence, it was practical to adopt double-pole for the long distance races.
This new "running" technique appears to be very high-energy, and may not be suitable for anything but short sprints uphill.
The use cases for short sprints uphill are few, so this may not bring big changes to the sport such as double-poling .
