He will be somewhere on it. If the first 3 bearings were taken from a single position then the target course would be defined as well.To find the correct location of the target at time 4 on that line/bearing you need to move to a (radical) different vantage point where the true bearing is likely to cross perpendicular to the red line.
I too find it hard to follow these steps, but they are mathematically sound. Personally speaking, the initially stationary method works the best for me. Less chance to get the procedure wrong in the heat of battle as opposed to the moving methods. But the moving method might be crucial to get fast moving contacts.

Take a compass and along this hypothetical course measure the distance between first and second line. Let course intersection with the second line be p1. Move this length now from p1 towards the third line. Mark m1. Now at that mark draw the parallel to first line intersecting the third line at m2. Now take the compass and measure the distance from p1 to m2. Move the circle so so it begins at m2 now. Mark m3 at the arrow end. It is the first point of a red line. For the other random course line do the same to have the second point for red line.

I am still perplexed.
I've been looking at the v1 of Kuikueg's method and it has somewhat cleared somethings for me.
But I am still confused by the part where you use a compass and marking these hypothetical courses.
I've also been looking at these two videos
trying to figure out what you guys are trying to explain to me.
