The 90 degree thing is true. In the astral, turning a corner will produce a lapse in continuity and snap you back elsewhere unless you have a minimum of presence of mind. Even a sleeping person will fail to do so most of the time, not to mention a hungry ghost. I think it’s due to losing sight of your objective and losing focus. I have experienced this phenomenon personally many, many times.
Interestingly, I don’t think this would work on a bridge like that where you can see where you are going at all times due to the lack of walls, even if you have to move sideways.
