I'm having a little bit of a hard time following what you're asking, but my impression is that you're saying aggression and giving examples of position and pot control with marginal hands.

I don't know how SABRE upped his aggression rate, but it may have come from a bunch of factors. Betting and raising more will increase your aggression factor. Check/folding more and cold calling less in position with marginal hands also increases your aggression factor. Making better choices in small pots OOP by folding shows up in your stats as being more aggressive. There is both a betting and folding component to aggression factor.

So to your examples, it probably isn't a particularly good idea to regularly fire multiple times OOP with second pair. You may be better off check/folding in those smaller pots as opposed to check/calling. Giving up in a small pot OOP is much better than creating a big pot and being faced with a tough decision later. Yes, you sometimes lay down the best hand, but that is the price of position. Build the rest of your game around putting other people on tough decisions in position and you will make that back. Sometimes you may want to check/call with a bluff happy fellow, but mostly you should refuse to play medium to big sized pots OOP with marginal hands. One thing you may want to look at is how you attack from position? Are you limping along on the button with drawing hands? Smooth calling your draws in position? Don't disrespect the button by limping with crappy suited connectors. Raise and attack from the high ground. Put other people to tough decisions with dicey second pair hands. Make them decide if they want to call a big bet on the end when their second pair is now third pair. Put them under your heel and grind.

When you have second pair like the TT hand, checking behind and inducing a bet or checking it down are perfectly reasonable choices. It isn't less aggressive because you aren't betting, it's using position to size the pot to the strength of your hand.
