When you see doubles like that, one is
generally a backup in lower orbit (visibly moving faster).

Yes, I noticed that but forgot to mention it.

I got a shot
once showing twin Iridium flares and the trail of ISS.

Cool!

The backups are noteworthy in that if you're on the centerline their
flares can reach magnitude -9.

I've seen a couple of -8 flares. Had to subdue the reflex of putting a hand
up to shield my eyes.

I saw one Iridium in the day. It was close to overhead, about a half
hour before sunset and the sky was very clear. It looked like a tiny
white dot that was visible for a few seconds.
