Step Mashing?

I am brewing a marzen this weekend. Some of the lager recipies I see call for step mashing, others don't.

Does step mashing only improve efficiency? Or does it change the profile of the beer when compared to a single temp mash?

Neat video. The science is beyond my comprehension at this point. I pretty much slept through science course in HS and college . But I am off the find part 2 of this video. Thanks!

But I am talking about a basic step mash which is quite different (I think) than a decoction. IE; mash at 140F for 30 minutes and then 158F for 30 minutes. What is that doing for me, and how does it effect the finished product??
