L2 shows shares trading, but you never know if that is a whole order or a tranche. You will see trades for 1 share at times. I got one myself, when buying 1M shares, I got two tranches of 999,999 and 1 share. You would see those on L2.
I also bought a few mil of HPIL and got 13 tranches of 99,000 plus some others. The tranches are just parts of orders filling. If someone buys or sells at 'market' the orders go through immediately, because the spread is not observed for market orders.
The spread has a bid, an offer, and a quantity. Those are guarantees that you can get at least that quantity at that price if you are within the spread with your limit buy/sell.
