What's funny about using this for an example is that it teaches exactly what not to do in the case of an unexpected "endo".
In the video, the host is teaching how to create a situation where the back tire lifts, hence weight forward, front brake applied - a front wheelie.
In a real endo you want to counter act that very movement, not create it. Butt backwards off the rear of the seat to move COG back. Better chance of that when on the hoods than down in the drops where your weight is already more forward over the COG of the front wheel.
Plus, the guy in the video is in a posture more like hoods than drops.
