That's what's lovely about geometry. It doesn't really need you to be on board with it. ?
Do consider the rules don't say you check the 'closest' part of a mini when determining if LOS is blocked - and in fact they can't.
If a storm trooper leader pointing away from the attacker has their hand (which is further than their head) behind terrain, it will still trigger a check. Practically determining the surfaces closest to an attacker for a complex geometry like a mini is simply not practical in real life.
Determining whether all surfaces facing the attacker and not self-occluded are blocked, is however quite reasonable. Humans are very good at distinguishing object outlines and overlaps with other objects.
Likewise there's a practical matter with regards to cover and elevation which the current rules take care of very cleanly. Since as a consequence of geometry the base is always blocked, then elevation always grants cover. Easy and simple to check.
Say that was not the case, and now you needed to determine if well and truely for real the lip of terrain blocked line of sight to the miniature (excluding the base for arguments sake), then now you need to get your head down and try to look up and see, is the unit not far back enough, that the height of the base still leaves their feet visible? Imagine doing this in a city street? In a narrow alley? It would be clunky and error prone and lead to general groaning and dissatisfaction anytime somebody moved units onto terrain. As the rule stands it's just as easy no matter how crowded or convoluted the terrain is.
Now perhaps non of this is what the designer intends, but it is how the rules interact. If being at the edge of terrain is supposed to be exposed, the way to fix that is to add a rule to the effect. I hope that's not the case however as it would become yet another dissincentive against ever climbing/clambering.
