Out of phase would mean the weights would be pulling against each other and it's more natural for the weights to swing in sync with each other. This reminds me of an experiment I saw once where they showed why the millennium footbridge started swinging once a number of people started walking on it. Humans naturally sync in step with each other due to the small movements, but being in sync causes further resonance leading to a longer swing cycle. Buggered if I can find the video now but it was on the BBC a while ago I would imagine they would also end up in sync.
