Could someone please explain the difference between the illustrated LOS examples 5 and 7 on page 55 of the V5.0 core rules? They seem the same, but example 5 states that LOS is degraded, but not degraded in example 7. In example 5 both units are on level 0 with a level 0 obstacle (brush). I example 7 both units are on upper level of buildings (level 1) and the rubble between them rises to level 1. So, in both cases the units and obstacle are all at an equal level, but in one of them LOS is degraded and in the other it is not. This is confusing, and the explanations seem to state the exact same thing.
