Notice that train is all rotary dump cars - painted ends on the head end of the first segment with painted ends toward the locomotives, there second segment has the painted ends away from the lead locomotives. Cars behind the mid-train DPU's have all painted ends toward the lead locomotives.

 

I looked at the video of the monster going through Zion.  It had two cars wth double-rotary couplers, so all locomotives, including the mid-train DPUs, had a rotary-coupler end adjacent to them.  

Is there any difference in the strength of rotary and standard draft gears?

I think they are the same strength.

However, this can happen if two rotary drawbars are coupled together:

If you watch quick enough you can catch the two cars that have rotary couplers on both ends to change the side of the yellow strip.
