But that doesn't mean that , if there's someone exactly a mile away, I can only see the tip of their nose and their toes.
I interpreted Jeffrey’s “shouldn't we be able to see only half a galaxy at the boundary of the visible universe?” as meaning something like: If he boundary of the visible universe coincided with the centre line of a galaxy, would this mean that, in principle, only half of the galaxy would be visible, if we had the ability to see it.
I suspect that, at that distance, any galaxy would appear so small that the point is moot; but Jeffrey’s question still stands.
