If a company provided X amount of liquidity to both sides of the market, even if the company itself only entered a position for a millisecond, it still provided necessary liquidity. It did so in a very efficient manner and turned a profit on that.
Saying that you dont provide liquidity just because you enter both sides of the trade is like saying that a cab going into and a cab going out of manhattan cancel each other out and provide 0 net value to their passengers.
