Most roses are grafted onto vigorous rootstocks. If you follow the branch with the different colored flowers down to where it emerges from the main stem I think you'll find that it developed below the swollen graft area. You'll want to prune off this and any other stems that grow from below the graft or these branches from the vigorous rootstock will eventually overtake the grafted rose bush. Of course, if you like the flowers, you can just allow it to grow. It will be a rambler rather than a hybrid tea rose but since you like the flowers, you may just want to do that.
