Understanding an explanation of a problem after listening to it is different from getting enlightened about the problem itself.
In the former case, it is not wrong to convey to others the very explanation that they understood, but it is likely to be wrong to convey one's own ideas about the matter to others.
In the latter case, whatever ways you explain to others about the matter, it is not wrong. To be enlightened about something means to be able to see it. Because you see it, you can see and explain about it in whatever way you like.
