Yes, absolutely.
What's described in the doc seems to be an algo for snapping up everything that's available across the various markets at one instant in time (rarely that much).
If you try to grab $100M when there isn't that much around, you'll have to wait until someone puts in more orders so you can trade with them. Any market maker (including human ones) will not let you trade again at the same price if someone's just taken out the whole market, so your next tranche will be executed at a worse price.
Dripping the orders into the market is very common, but of course you leak the information by doing it. For the HFT however it isn't as obvious as seeing that an order must trigger an order on another venue (NBBO requirements) and just rushing to pull your orders from there or trading ahead of that order.
