75,000 options vesting in 2013 and 100,000 vesting in 2014 probably explain the year as adviser - i.e. fiscal year 2013 ends October 1, 2013 so one year from today is probably adequate for those options to vest and may have been an equitable way to resolve severance negotiations.
Why even have a vesting period if the company is going to give them to executives anyway? If Tim wants Scott out, then why pamper him with free money? It's not benefiting shareholders.
I suspect the stock options were to help maintain the illusion of stability and unity in the period before and after Jobs' death. 75,000 shares is a lot of money for one person but if it keeps the stock price a couple of dollars higher it is a net benefit to shareholders.
Apple has more than 939 million shares, maintaining $1.00 in share price is nearly a billion dollars in shareholder value.
