I would not worry about the branch for a few days. The main thing is you want the swarm to stay so minimize disturbing them for a week or so. Did you have some drawn out comb in the hive? That helps anchor them. When we hive a swarm we try to make sure there is at least one frame with drawn comb, We also close the hive so the bees can not leave and we feed them for a couple of weeks. After they have started laying eggs and there is brood they usually settle in. We have also used a frame of capped brood a few times and that also seems to help.
The hive you think swarmed should be checked so you know what you have. Theoretically the swarm left a bunch of queen cells and at least one of those with hatch then you need to wait while the new queen matures, has her mating flight and starts laying. So you could be looking at a hive made weak by the swarm that will continue to dwindle for over a month until new bees begin to join the colony. It might help to give a frame of capped brood to this hive once a week for the next the next 4 weeks or so until the first brood of the new queen begins to forage.
