Because it's way more efficient to do the polling C-side and fire off events, than for 5, 10, or 100 addons to run identical OnUpdate scripts in Lua. I mean, in theory you could just use OnUpdate for everything instead of responding to events... but I'm pretty sure even the UI coders at Blizzard, with their inexplicable love for ugly and inefficient code, would laugh at you if you did that.
