EPTI made a 3 min video which demonstrates how my Dota setup lets me switch from passive to aggressive stance and some of the situational benefits of being able to use both of these at once.
To do this you need to be in Standard autoattack mode and turn on Quick Attack.
You toggle between the passive and aggressive stance by tapping your Attack hotkey, which functions as if it switches autoattack to Always, and your Cancel Current Action key, which functions as if it switches autoattack to Standard.
This allows you to use gameplay techniques from both Standard and Always autoattack modes, which people previously achieved by having a simple script (before scripts were disabled by Valve).
