Nonsense.  A non-centerline-thrust twin engine airplane can't maintain
heading with one engine idle and the other producing takeoff thrust
below a known speed called V_{mcg}.  There are procedures for THREE engine
takeoffs in FOUR engine airplanes, involving symmetrical thrust early
and addition of thrust from the third engine as speed builds up.  A long runway
helps, too.

I'd imagine that anyone trying this in a twin would end up in a smoking
hole next to the runway.
