I don't think this question is very well explained.
Here is my take on it.
I used to live in England - I spent some years as a child in Nairobi (40 miles from the Equator) and now I live in Texas - about halfway between (in terms of latitude).
In the UK, the moon looks like this
The tips of the moon arc are nearly vertical above each other...but not quite.
I was an 11 year old in Africa, it looked like this:
Notice that the tips of that arc of light are almost horizontal.
And in Texas, it's more like this:
The RE explanation for this is very simple. The moon didn't change - it's just that you're standing on a ball - and if you're on the equator, you're looking at the moon "sideways" - when you're up as far north as England, you're standing nearly "upright" - and here in Texas, it's halfway between.
I always wondered (before I went to life in Africa) why all children's books (mostly written in the UK) show the moon in a vertical orientation - but various people in Africa and Central America have these traditions that the new moon is as "boat" that carries the gods across the skies. As a kid - seeing the "upright" moon - that made no sense at all. But the first time I saw the moon in Africa, it all "clicked" and I realised that this rotation explains all of those weird legends.
If you look carefully at photos - you can also see that it's not just where the bright part of the moon is - it's also the pattern of craters, etc.
In Northern Hemisphere countries - people always talk about "The Man In The Moon" because the crater and maria patterns look a bit like a face. But in most places south of the equator, people see a rabbit or a hare in the pattern. That's because, in the southern hemisphere, the moon looks completely upside-down compared to what we in the Northern hemisphere see.
So...how does FE explain this? Simultaneously - the moon looks "the right way up" in the North - "sideways" at the equator and "upside down" in places like Australia and South Africa.
The RE explanation is quite simple.
The FE explanation?
(I'm betting it all goes quiet at this point...anyone want to answer this one?)
