No - it would be charged as one through journey - because it's configured
as an OSI, and that's what happens at OSIs - 'closed' journeys are
re-opened when touching in at the second station/gateline, or in this case
on the standalone validators en-route to the Tube platforms. (Am prob up
that way shortly, if so I'll try it out in practice.)

Looks like Boltar has missed about three or four years worth of on and off
discussion here explaining exactly what happens at OSIs.
