On the Flatter Plane Angles, Angled Hinging approaches Horizontal Hinging. Hence your ability to produce Horizontal Hinging with the Feel of 'No Roll.'

On the Steeper Plane Angles, Angled Hinging approaches Vertical Hinging. Hence the necessity for a more pronounced 'Roll' Feel to produce the Horizontal Hinge Action.

Thanks for this Yoda, it makes a HUGE difference in translating the 'feel into real'. This post has saved me a potential few months worth of frustration !!!
