>I'm pretty sure a flat cable cannot be a twisted pair
Anon, stop thinking in 2D. We're in 3D.
They're flat, like plywood is flat.
Not perfectly flat or close to it like a flex cable is, but flat enough.
>If they are then wonderful but I just don't see how that's physically possible.
Twisted PAIR, with multiple pairs in the cable. With the pairs in a row, you get a flat cable.
See pic rel, it's really that simple.

Now you know.
