If you look the end of the track.
Its easy to see that top and bottom sections, are much wider than section in the middle.
When one cuts steel with angle grinder, cut groove expands wider when steel is getting hotter. But, when steel starts to cool down, it always shrinks little more than it was expanded.
This shrinking makes cut off wheels to get stuck and jump. Specially when cutting thicker materials.
When you cut through the tracks thicker section, keeping groove equally heated as possible. And reach the narrower section, it happens that wider parts of the track resists shrinking forces more than there is " power to shrink " in that narrow area.
Groove starts to open wider and wider, like a flower.
Shortly " Remaining sides in the thicker area, resist shrinking. While sides of the narrow section are expanding, this makes groove wider and wider. " You can easily cut straight through when groove forms to V- shaped and guides wheel to the bottom.
So, " trick " is to do it with minimal breaks, keeping it warm all the time. Profile of the track does the rest.

Yes the expansion, petal-like, relieves pressure that would normally pinch the wheel.
But 9 out of 10 can't hold a 3600 RPM 7" wheel so well on plane.
I watched a good deal of the 30 minutes; especially after beginning following those scribed lines.
...we'll learn more by wandering than searching...
