Short answer is "yes" more or less the same thing.
As above, we used to call them "running takeoff" but I am not sure if that is only on this side of the pond. Likewise, at the bottom of an autorotation with forward GS maintained, we used to call that a "running autorotation" to differentiate it from an auto to a spot.
