The puppy will be fine. In fact, it's better if you're both involved in his training.
Edit: I meant in the aspect of basic obedience and whatnot. Though I do know several dogs who are handled by different people in IPO (usually husband/wife teams), I'm not sure how it impacts the dog's training at that level.
