It implies that there are two people with a difference of opinion.
If it is regarding something subjective, then neither can be said to be wrong.
If I, a Star Trek fan, disagrees with a Star Wars fan about which is the better science fiction franchise, does that mean that one of us is objectively wrong? Of course not. The Star Wars fan's claim that SW is better is just as valid as my claim that Trek is better.
The only difference is that with morality, most of us hold the same opinion, for example, that murder is bad. But that doesn't mean it is objective. As I've pointed out, most people have the opinion that Battlefield Earth is a terrible movie, but that doesn't mean that it's objectively true. It's just that people very often mistakenly believe that a viewpoint that lots of people hold must be objectively true simply because it's a widespread viewpoint.
