Maybe it's just conservation of angular momentum: if you look closely, you can see that the spin axis and the way she applies the force aren't perfectly tangential to the object's axis, so the lower point of the T-shape is "bouncing" between many positions. If I'm not mistaken, this is explained by the "intermediate axis theorem".
I'm sad because you explained it so well. I was expecting something life changing explanation and lot of discussions around it but the simplicity and truth in your answer annihilated the conundrum. I can think of the body having a kind of oscillation in its "angular momentum" around some mean position of the angular momentum. Thank you.
