That is the epitome of stealth: you don't have to be invisible, or even unseen, just unnoticed.
Actually, that's how the guards in Assassin's Creed operate: if you're not known yet, you can just walk past them. Unless, of course, you start causing a ruckus by pushing people or climbing buildings. That's suspicious stuff, and attracts attention.
You don't have to show your presence.The only things you have to show are the results.
