Point of correction... he didn't have to resign from the EC in order to purchase shares, he already had those shares prior to being appointed. He resigned shortly after he was appointed and my sense is that he does not want to be hampered by the trading restriction that comes with being an EC member in the event that trading opportunities arise. Someone might view this as a negative -- if he knows that equity might get something good at the end of the day, why not just ride till the end?
I on the other hand would view that as a positive (coupled with the fact that the EC did not object to the POR on 5/22). I'm guessing the POR has been amended to reflect a more reasonable distribution to equity. Just a guess though, and I've been wrong before.
