I've drafted up an example.

If you have different opinions of a single subject, you can write them in two answers. But if you have multiple reasons supporting the same opinion/concept, there should be a single answer.
For the situation which triggered this question, MikeFoxtrot's conclusion is the same but discussed in two different aspects. I agree with Federico that it should be (and now is) in a single answer.
