Impossible to tell from the slide, because such a seam only occurs at one longitude, and moves over the day.

However looking at other sources, it seems Starlink (having more satellites) actually wraps the orbital planes 360° around the Earth (vs Iridium's minimalist 180° configuration), overlapping both North-moving and South-moving satellites in the same sky simultaneously. This means the Iridium seam disappears entirely. Neat! TIL.

Another problem that vanishes simply by being "hardware rich."
