I disagree that it is a mating dance. Alot of fish do this as a sign of aggresion or dominance. It might get associated with clowns mating because one is establishing dominance over the other. but you will also notice they will do this toward any other fish that gets in there "turf". My observation has been that they will do this to other clowns but it seems to subside after they pair up weather they actually mate or not.
The clown dance is a bit special though.
First the female (female to be) will express her dominance by charging. As she charges the male he has a seizure (as you put it lol). This sign from the male is submission. He is saying, "Oh all powerful female don't harm me I'll do as you say." Then the female will respond with a sort of wiggle that I like to call, "doing the funky tuna." In any case it is an interesting ritual and something you shouldn't worry about. In addition, excellent question
