I realise that in addition to the stereo to mono conversion, this
particular example is also converting sizes but as far as the
electrical side of things goes, does the adaptor simply short the left
and right channels together?

It rather depends. Amplifier outputs are usually low impedance and may not
like being connected in parallel. So to be safe you'd use a resistor in
each leg to prevent distortion. Going the other way round - mono to
stereo, so two inputs are connected - is usually ok.

Wouldn't plugging a mono plug into a stereo socket achieve exactly the
same thing without an adaptor (assuming the plug and socket were the
same size)?

You'd be hoping the single tip mates with the twin stereo contacts. Which
it may or may not do reliably.
