The general concensus is that the entire left branch is light armor despite plate armor technically being "heavy" in all our opinions. Bethesda probably just fudged that one for balance sake.
Personally I'm still concerned that to get the final perk of each tree (the ones that have two branches meet at the final perk), requires you to fill out both initial branches. We've heard you don't have to, but it's probably something I'll worry about until I see it proved otherwise when I'm playing myself.
