Dawn Redwood

purchased a dawn redwood from mail order nursery they sent the 3foot sapling with the very tip of the leader cut off, stating it was to prevent it from breaking while shipping. I asked why not anchor it better and use a longer box. but damage was done, they left about a half to inch stub, in the 2-3 weeks that I have had it, one branch is almost upright, looking like it is becoming the leader but now the stub has new growth, I want this to grow properly, do I cut the stub back very close to where the lower 2 branches are? so the leader continues?
