you're asking a good question, that I'm not really qualified to answer, but in short I think no, that's not the explanation. what you're talking about is a general relativistic phenomenon: just as it takes a few minutes for the sun's light to reach earth, it takes an equal amount of time for the sun's gravity to get here, and by then the sun has moved on. However, I don't think that is responsible for these orbits.
