Why McMaster, why?

Somebody explain mac nursing to me. Why do they have one bscn program with two identical streams, both in the same location and require you to apply to both? I didn't realize this and only applied to the main and didn't get in with a 93.5. But you can get into the Momac stream with a 91? WTF? Why do they do this two streams thing? Is the whole thing a collaborative program or just the Momac stream? I have heard people say that Mohawk staff teach both streams and that McMaster staff teach both streams. So what's the point?
