is nonsense.
If you peer out any of the flight deck windows on that particular pushback and find that you're looking along the taxiway centreline, it means you've been pushed onto the grass.
If you're still having trouble visualising that, think of it the other way round - for your mainwheels to be (just) on the edge of the concrete, you need to have about three and a half metres of your nose still on the right (terminal) side of the yellow painted line.
Would a picture help?
