Tai Chi Classics say: "If you look up it seems higher", "If the opponent raises up, I seem taller", etc. One has to take this into account when they are both doing form and applications. It is "by the same token" in both Tai Chi Application and Tai Chi Form practice, even though most think they are at opposites. Because I am much taller, I will be able to crush down on Master Stephen Hwa during application if his body structure is not good. If I'm not a "winner" in the execution of Form practice I will be a "loser" in the execution of an application.
