I guess I just assumed they would be skipped over. The whole metered space issue still had me thinking about these two methods though, hence the new question for clarification.

The reason for preferring to work in projected meter space is that the
grid (like an image pixel) is rectangular. Very simple to match the grid
with a projected image. Lat/Lon grids are, uh, NOT rectangular. Working
in that space is a nightmare. :-)
