Hi Pineapple! You are more or less correct, it has the same meaning in this context. The thing to remember about the phrase "they keep good company with" is that whoever wrote the phrase is expressing an opinion or value judgement ("good"). So in their opinion, Charlie Chaplin, Buster Keaton and Danny Devito are all good people who you would probably want to be in the company of. "They bear a resemblance to" is more of just an observation. You can "keep good company" with people or creatures which you do not resemble. It is more about the writer's opinion.
