Having the maps upside down may not fuss the veteran observer but for the novice it is entirely confusing. Especially, if they are looking for the stars in a constellation the wrong way up. And when you turn the maps over, all the text is upside down and hard to read at night.
One of the reason's I did my maps as a Southern Hemisphere observer was to correct the orientation when looking north i.e. the constellations are the right way up (but upside down for a Northern Hemisphere observer). Of course, the embedded text is also the right way up so you can read it easily. As mentioned by Patrick, when facing south, the constellations nearer to the South Celestial Pole are seen to do a complete rotation around it so the orientation will change constantly. On my maps, I left these constellations with Celestial South down as they are best seen when they are highest in the sky.
I also designed each page (A4 size) map and data so that they could easily be slotted into a plastic sleeve type booklet to use outside at night.
