Yes, if your opponents start 3betting you wider, then you can narrow your opening range a bit and widen your range to call their 3bet, as well as add in some 4bet-bluffs (if stacks are deep enough), as your opponent's 3betting range will be wider than normal.

Since we will be using this smaller raise size against shortstacks, it is really good for us if they 3bet very wide; we will get maximum value from our great hands. If we are opening small versus a player who is not a shortstack, but 3bets a lot (more than he probably should), then getting him to 3bet us even wider means that his leak becomes magnified. In other words, if someone is 3betting us in a spot 15% of the time, and then he sees us open small, so he widens his 3betting range to 25%, well, he's exposing himself to re-exploitation for a lot more chips than he will be exploiting us for.

Another situation for making your raises small, which I didn't have time to get into in the video, is when you are stealing the blinds from the CO or the BTN. While you might induce some action from a smaller sized raise here, you will have position against your opponents a lot of the time, which will work to your advantage. Furthermore, by keeping your sizing small your opponents have a dilemma: Either they make their normal-sized 3bet, in which case you don't NEED to call or 4bet all that often to prevent them from exploiting you, or they will size down their 3bet proportionately to your open-raise size, in which case you can call pretty wide and own them postflop when they have garbage (which will be a lot of the time, if they are widening their ranges a lot against you).
