He sold that over two months and the overall market was much stronger then. Also those sales were pretty much required for taxes and thus did not send a negative signal to the market. If he sells large amounts of tsla shares to buy twitter, this will be a negative signal -- any other tesla shareholder can sell tesla shares to buy twitter, and why wouldn't they when the tesla CEO is doing it.
It is still possible that he tries to raise 21 billion by selling stock but I doubt it. First if he actually wanted to do that, he would keep quiet while selling and then come out with the tender offer when he had the cash.
