Now, because of the Richmond loop there are indeed two routes to
Staines, one clockwise and one counter-clockwise (actually three if you
count via Weybridge, but I think it's forbidden). One would have thought
that 'not London' would force one to go clockwise round the loop. So who
was right? Logic or the official? And if the official was right, what
can be the purpose of disallowing London?

AIUI "London" is the London terminals rather than the conurbation,
especially as your journey started within it.

That's what I'd think usually, but in this specific case I can't see any
reason to forbid London terminals, especially as Waterloo is the only
London terminal with services to Staines. If London always means
terminals, though, maybe this is just an anomaly...
