That would be expected.  If several objects started at the same point 
(the satellite) with an initial velocity in different directions, you 
would expect them to orbit the earth and then cross back through the 
same original point.  So they should all come back together to the same 
point one orbit later (almost exactly 24 hours).  Unless some pieces get 
a different force applied to them versus other pieces.  Such as due to 
solar wind/pressure.

Although you wouldn't necessarily expect them all to arrive back at the 
same moment.  Some would have a faster or slower orbit.

But coming back together makes sense if the video is more than 12 hours
