The Dot in Tai Chi Sword

When learning the bayonet in the military, they teach you to stab, twist, and retract. In Tai Chi Sword, there is a fundamental move called "Dian" or "To Point." However, references say that it doesn't mean to point like one might point their finger but to draw a point like one would do when writing calligraphy. In Chinese calligraphy, when you draw a point, you twist the brush at the end of the mark to cleanly end the mark, making it look like a teardrop. Could this be a core mechanic of the Dian?
