It's to keep people from getting away with extrememly short posts like "lol", "nope", "yes", and the like. Also so that you don't get just a picture or video with no explanation as to why it was posted(yes a picture is worth a 1000 words, but it isn't always obvious what those words are).
There are times when a one word post is useful. Like if the thread is based around low content posts (The "Each Post must contain a Picture" Thread comes to mind). Hopefully the mods take that into account when they are reviewing a post to see if it should receive some sort of warning.
The only real problems I have with it is that sometimes a short post words much better than a long-winded one and that people will also add something like "random stuff so this post isn't low content" after they post something like "lol". These aren't that bad though and are better than the forum being filled with "lol"s and "no"s everywhere. Sure the Escapist isn't the bastion of Internet Intellect that some people make it out to be, but at least it's a bit more polite and well-kept than other sites out there. That counts for something.
Edit: Course I've never run afoul of this rule because if I'm going to make a post, I'm at least going to make sure that it's worth the effort and thus has more meaning than a simple one word response. It's one of the easiest rules to abide by, so long as you try.
