(voice of Ronald Reagan) "There you go again......" Calling the Mr. Red reckless. Call him a Zombie, fine. He's skiing at a constant speed, barely taking any slope width. Unaware, sure. Not reckless.

Answered below. I'll give it a -2 to keep us all even.

In practice, when one skier/rider is overtaking another, the vast majority of the responsibility for avoiding problems should be on the person doing the overtaking. They have a choice to slow down or take another line, and are in a much better position to react to the 'ahead' or 'downhill' person. If someone is moving significantly faster than you are it can be awfully tough to notice them coming up from behind and actually be able to react in any kind of meaningful way.
Overtaking is a difficult thing to define. It gets into uphill/downhill and doesn't account for the current problem - a skier cutting across a trail and hitting someone minding their own business skiing on their side of the trail.
With Grey's pathway diagonally across the trail to the left side, you could say like Tpj did, that Grey was overtaking red in trying to get to the left of the trail.
Seems like we're better off with a "be aware" "look" type of rule.

Here's another way to look at it. If you draw lines parallel with their direction of travel and through each skier, and then two more lines from each skier to the other skier. The angle between the parallel to direction of travel and to the other skier will be closer to zero degrees for the skier who is not "ahead", and bigger for the skier who is ahead.
Possibly beyond could answer this string puzzle. I sum up and go back to the train analogy. You're heading to the crossing, train not there yet, but it's ahead of you. It's in the direction toward which you are moving and your paths will intersect.
Grey's direction change puts him on a path to the left side of the trail. Red is already over there just uphill. Tip the picture sideways - Red is ahead of Grey.
Put another way: Red is closer to the place Grey is going to. Red is ahead of Grey.
Your other point about always looking over your shoulder for every turn. (previous page)
Clearly that is not necessary or desirable. If you're making regular turns in a constant or near constant width on the trail, you've established a "lane". It's predictable you'll stay in it and fairly easy to stay away from you. When you suddenly, like Mr. Grey, veer out of that and head across the trail you should look uphill to make sure no one is coming.
In other words, you've suddenly decided to cross the trail, and like crossing the street you should look in direction of traffic. Uphill.
That's a pretty simple thing to put in. When crossing the trail, look uphill.
