Travel between stations beyond London and high speed catchment stations..
For travel between a station listed in Table A [basically any station in
Kent] and a station beyond London, only tickets routed “Not Valid On
*HS1” (00130) will require the passenger to purchase a Preview
supplement. All other routed tickets, including “Any Permitted” (00000)
are valid for travel on high speed services. This will apply to longer
distance flows (such as Ashford International to Derby) which are routed
“Any Permitted” (00000).

So it is clear that as long as the ticket is routed Any Permitted (which
a Ashford-Kentish Town ticket is) then it is valid on HS1.

Actually, that is very ambigous regarding Kentish Town as I don't
think you could regard it as a 'longer distance flow' *or 'a station
beyond London'

Not a 'longer distance flow', but it shouldn't be too hard to
establish that it's a 'station beyond London' - trying to get out of
the barriers on a London Terminals ticket, and keeping the PF notice
you're thereby given, should do the trick.
