The two aren't contradictory.
The problem here is a more wordy reading can't fit there, because as far as I'm concerned, there's a limited area in the "help center" that moderators can modify, and the rest are topics that are discussed the same way across different SE sites.
There are some "meaning" questions we don't allow, and some we do. The ones we don't are, just like non-allowed questions in any other topic, questions that don't align well with the site's mission.
We don't want to replace a dictionary. That's one of the things our site definitely doesn't want to be. Sure, helping out learners is good, but becoming a dictionary for them isn't helping them.
Thus, we close meaning questions that can be looked up in a dictionary and be answered. This is usually off-topic:
What's the meaning of [word]?
The governors are perplexed trying to [word] foreign ambassadors. — GNN
What does [word] mean in the sentence above?
Usually, any other meaning questions whose answers aren't going to help anyone are closed as well:
What does "woudl" mean?
If only I could save some money, I woudl have bought a new car.
This is a sentence a native speaker used in a chat, so it must be flawless, right? So, what does "woudl" mean?
The question above is just about a typo; it's unlikely to help future visitors.
Having said all that, there are quite some meaning questions that are acceptable on ELL, even perhaps more than what's not. You could've looked up the tag and see this is definitely about meaning and definitely acceptable. It's about something a simple Google search or a dictionary would not tell you reliably.
