I thought the point was to expel the old grease and cavity isn't sealed. Pumping too fast and without spinning the wheel is the issue.
To expel the old grease, you would have to pump a massive quantity of grease in. All the grease from behind inner bearing, in the cavity between the bearings and the grease in the outer bearing would have to be flushed out the front. If you don't get it all, (and you won't), there will be old grease from the inner bearing now in the outer bearing. I suggest just doing it right when you do the annual bearing inspection and forget the useless and troublesome grease fitting.
