Well their scheme does leave some questions open: Does 3.00 need to come after 2.99 or can there be a 2.100? Or if its more like 2.8.x: Can ever be a x.x.10? (we are talking here more about the scheme that actual blender releases)
How I currently understand is its just 2 numbers and 2.8 is a simplification for meaning 2.8x.
