Kos vs Pierce questions

Thought the fight was a close match, personally thought Pierce won but I don't think it was a bad decision, the fight was close.

Here's my 2 questions -

1 - On the undercard Herb Dean took 2 points away from Alex for his 2nd low blow after 1 'strong' warning.   In this fight he warned Kos in the 2nd round about keeping his fingers in.  He then followed Kos to the corner and warned him a 2nd time, stating that he'd been doing it all night long.   In the 3rd there was a pretty bad eye poke and Herb does nothing?    Thought that was a little odd.

2 - I don't know how the judges see everything.  In the 3rd round Kos nails a double leg takedown and Joe R basically says that probably won him the fight.    I would say that the spinning elbow Pierce threw did more damage than any double leg.    We here it all the time but I always find it odd that after a 15 minute fight they think it was won on a takedown with about 10 seconds of control.    If the guy getting taken down gets right back up I don't think it should could on the scorecards.    But over and over again it does.
