Relativistic beaming! https://youtu.be/zUyH3XhpLTo?t=490

So that would mean that the right side is tipped slightly away from us, right? Because the matter in the accretion disk starts approaching us at about halfway down the ring on the right side?

Yes, from paper 1:

"Third, adopting an inclination of 17° between the approaching jet and the line of sight (Walker et al. 2018), the west orientation of the jet, and a corotating disk model, matter in the bottom part of the image is moving toward the observer (clockwise rotation as seen from Earth). "

Already watched the video, thanks. However in his example the disk is not perpendicular to the viewer so the beaming makes more sense there I think.

On the other hand, "almost exactly from the top" is not the same as "exactly from the top".
