Irrelevant.
My question is: do these three videos appear to show the same phenomenon?
This one is of an alleged satellite:
It looks very much like the videos of NEOs to me.
Here are two:
Yep - can't tell any difference at all.
Can anyone else?
If so explain what the difference is please.
Why is this request so hard for you?
There are significant differences visible in the videos, including telescope field of view, camera exposure, object brightness.
The significant difference for the purposes of NEO versus satellite is that the object in Video 1 increases in brightness over the frame, explicitly stated by the video poster as satellite coming out of shadow. The objects in Videos 2 and 3 do not.
Whether or not one "can't tell any difference at all" depends on how much attention and care one takes in one's observation.
Another indication of attention and care is the selection of three videos to make a point when the data space is much larger. But care and attention to detail ... not really a thing here.
