Thomas says a lot of nonsensical things during those 4 minutes. He keeps on continually referring to the trading prices of GameStop, basically belittling the market price of $100~200 and continually insisting that it is a company worth a lot less (somewhere below $50, I forget). Even though he runs a brokerage firm, his personal opinion is very non-neutral and he wants to dictate a market direction.

He says "so short squeezes are illegal" at about 3:30
