When person A has been working on a technical problem for some time, they may have a greater awareness of the context than person B that's just heard about the problem. If A has the contextual knowledge but poor communication skills, they may forgo the high-level discussion that B needs to adequately understand the problem, or the system as a whole. B needing that high-level discussion doesn't mean B isn't a good developer, and A being narrowly focused on implementation details doesn't mean A isn't a good developer. But they both need to be able to meet each other in the middle to be most productive.
