Fixtures in a group are stored with a selection order, which is used with Shapes, Fan, and Overlap. You can also store a 2D position layout for fixtures, giving the actual physical location of fixtures for use with Shapes or Pixel Mapper effects or when selecting fixtures using patterns.
Why it should be changed:
It might be worth indicating here that the fixture order in a group is just a one-dimensional view of the two-dimensional position, specifically the X position, therefore changing one effects the other. Using the Group Layout Editor can be a useful alternative for updating the fixture order but the relationship between these two has caught out users in the past.
I have noticed that this is mentioned further down in the Fixture Layout section however this earlier paragraph tends to suggest that they are separate (specifically the word "also").
