Yep. That is what perplexes me as well. They can fix a title on an article they can change the content in an article post, but not on a comment post. Maybe the software is set up that way or maybe it's a policy by FR. Comments can't/won't be altered, only removed if inappropriate.
Either/or; it's probably just as well.
