Some aren't and you have to grab the signal as they fly over, but others

Impossible, unless they are infintely far away. :-)

Geostationary orbit gives them almost a third of the planet each, if you
can remove the distortion round the edges. Allowing for overlaps, half
the planet isn't too far off a usable result.

That's why the satellite broadcasters only really need 3 satellites to
cover everywhere except the Arctic and Antarctic. The extras are for
bandwidth.

I see where you're coming from, but he did say "between them".
