As far as I understand it from what was said when it was introduced, yes. It required massive service
changes on the London Bridge - Croydons - beyond route to accommodate the Overground timetable,
and presumably a clockface timetable on the individual branches was a goal.

(And Sydenham - New Cross Gate is 12tph - at a very even pattern too - which must be close to the realistic maximum for the line I'd have thought? If I remember right from when I lived there that's
double the service there was before London Overground)
