It is not legal for insiders to purchase on the open market during a quiet period. Regardless of how he said it, it had to be options. The only period in which insiders of a public company can buy/sell on the market is within 30 days after financial filing. Anything else would amount to insider trading, because they would be trading with insider information that is not public. I know - I used to be a director in a public company, and them's the rules... The filing does not say he purchased on the open market. Check with the TA - it will have increased by 25M shares.
