Many schools of combat have different approaches, but based on my experience and knowledge, displaying any form of passivity, in order to try to set up for a successful strike is wrong move, and the dangerous one. Every school of combat and self defense teaches one to seize initiative, act fast, and act hard as soon as the chance arises. We are not bunny rabbits, or antelopes, whose defensive strategy involves putting the predator in a "Gotcha" mindset, in order to surprise them.

You're assuming the mindset of the attacker, and making a classic mistake when teaching self defense - giving a technique that is not multidimensional.
