I take it the 'Hi Level In' and 'Hi Level Out' is where the speaker
output wires from a stereo amp are routed for a normal 'sub/sat'
stereo setup? (amp - sub - speakers.)

Yes. I envisage the subwoofer would rely on the main amplifier power
to move the air, using only active circuitry to provide crossover and
phase adjustment.
Not quite. The sub has its own power, those connections may provide
high-pass filtering for the main speakers, which are fed from the Hi
Level Out terminals.

I don't think I was being clear enough. This would most likely be the
case if the high level in/out was used, with the internal amplification
only being used when the equipment was supplied with a line-level input.

I'm not aware of any subs that do this, but I suppose it could happen.
In the designs I'm familiar with, the speaker level input is filtered
and split. Then one side of the split signal is sent to the high level
outputs to go to the main (LR) speakers, and the other side is
attenuated and fed to the onboard sub amplifier.
