See this question. One user has posted 2 answers. It seems that they are merely different sources for answering the question. I'm wondering if it would have made sense just to merge these 2 answers into 1.
Are there any guidelines or is there any policy regarding when to post an additional answer to a question?
See What is the official etiquette on answering a question twice? on MSE. The top answer there states:
When you have two distinct answers.
It's better to post two different answers than to put them both into one answer.
[snip]
If you put two very different answers in one, then one could be a great answer, and one could be a terrible way to do things, but the upvotes (or downvotes) on the good (or bad) answer will drag the other along with it to the top (or bottom).
Personally, i think that in the case you gave, the answers are different enough to warrant being posted separately.
