It just occurs to me why you might not be allowed to have more than
one item connected to a shaver socket. Suppose, unlikely as it
sounds, that item 1 fails so that the 'live' wire touches the case
whilst item 2 fails whilst the 'neutral' wire is doing likewise,
then you could touch both and not be protected by the transformer.
Hence you need a separate transfromer for each socket.

Absolutely. If you want the safety an isolation transformer gives,
then it must be restricted to one device per transformer. Standard
practice in the days when they were used in TV for musical
instruments and there was a very real danger of this occurring with
cheap guitar amps etc.

I've missed the point on this somehow.

How would being able to touch both the live and the neutral suddenly be
as bad as if the transformer were not there and you did likewise?
