There's some truth in that, but I'm not sure it's kinetic, an effort to create movement. It's "presence," as you said – something static that stores energy in the embrace and more clearly communicates body position. People tend to mix up the two and assume that presence means push, but the idea is for the other partner to provide the same presence so that the two cancel out and create not movement but "isometric tension" or "compression," similar to the simultaneous push and pull on a handgun in the Weaver stance – it adds control and stability.
One Argentine guy here got grumpy about followers here complaining that he was torqueing them with his arms. His feeling is that they were just feeling presence they refused to match. According to him, Argentine women match him. I've certainly felt that from Claudia Codega, Graciela Gonzalez, Ariadna Naveira, and Sofia Saborido in classes, though maybe they switch it off at the milonga (but I rather doubt that). I think non-Argentine women or their teachers have weird hang-ups about being "too present," which might be cultural.
