Curbed satellite trajectory - GLOBALSTAR M006 & 060 ?

Dear all,

I have a question, which may look dumb, but I must admit I never saw
that before...
I was smoking a cigarette outside, in Montfuron (France : 43.838° N,
5.696° E), when I saw what looks like a satellite in the Big Dipper tail
tens of seconds before 19h15 UT. I wondered if it could be a Starlink,
seen its magnitude (+3.5 to +4.0), but I very fast realized it was far
too slow to be one. But gazing at it, I suddenly had the impression its
trajectory curbed and took a nearly 70° angle without really changing
its magnitude, before disappearing... (see attached picture if allowed
on the list)
I must admit I did not understand at all what it could be. I wasn't
drunk or drugged, I am observing the sky as an astronomer for 25 years
now, I have seen strange things (NOSS triangle formations, etc.), but
all of them found an explanation... For tens of minutes, I could not
find any, so I realized I had observed the first real extraterrestrial
shuttle!!! ;-)

But a few minutes later, I checked on Stellarium, and realized there
were 2 GlobalStar satellites (M060 and M006) which seems to pass in the
Big Dipper Tail, with the two trajectories (before and after the curb) I
observed. On the model, there are not exactly passing at the same place
at the same time (which must have been the case to explain what I
observed), but I was wondering if you had a guess on the timing accuracy
of such satellites predictions?

Thanks in advance for your answers!
Best regards,
karl
