Well, some questions probably are. But that's like asking "are some questions about swords?" For the sheer number of questions these systems get, it's inevitably going to be true at some point.
I don't see any particular problem in practice with these tags. There's a lot of cases where the system overlap is sufficient that you actually can answer for both, or (particularly for non-strict RAW cases) something from one is easily compatible with the other.
The question you gave has list answers because there's more than one way to do the thing in question. There also isn't a good way to make the question specific enough to narrow it down to only one way of doing said thing, until the person asking question already knows how to do it (which would defeat the point of asking the question). Both answers are also pretty detailed already, I'm not sure how much more could be added without making them overly long.
I don't know, I'm just not seeing any problem in this case. It looks like things are working correctly.
