It was at the IPO. This is not new. He didn’t sell 30 million shares Friday and another 30 million shares today.
Just the 30.2 million shares everyone was told he would sell at the IPO. The sale is to raise cash to pay the taxes. It is very common.

I said he personally still owned over 30Million shares, not that he sold 60 million.
