That's how I use these, but that's certainly not nomenclature shared by all on the list (the only difference is that I have an "estilo del centro" instead of "apilado", because there are also dancers in that style who have the appearance of lean but don't really lean; dancers dancing "apilado" are for a large part a subclass). "Nuevo" certainly doesn't elicit many references to *just* the Naveiro/Salas systematic approach (which I like) to analysing what's possible and what's not from position X (from here if I'm close to the follower I can dance an alteracion or a molinete, if I'm not blocking her I can lead an ocho, overturned ocho with back sacada, overturned ocho with gancho, etc.; if I choose to pick the alteracion depending on what I lead I can follow with walking (with different rhythmic patterns), a front boleo, back boleo plus front sacada for the follower, volcada, etc.; if I pick any of these I can follow with...etc.). As I said it often refers to anything perceived as non-traditional which someone doesn't like, anything danced on a social dance floor that shouldn't be danced there, any dancing that's navigationally challenged on a social dance floor, for some anything in open embrace, etc. Quite the scapegoat. But of course it's only *a* point of view. It is pretty close to what I know some Argentines use, but good luck using that nomenclature in the US (where "de salon" has taken a completely different meaning in some circles, becoming the shorthand for Miller-style "tango de salon estilo milonguero"). That's always going to happen. Tango is by and large a dialect continuum; from Wikipedia: Pick your features and start labelling the isoglosses. The probability that your map and labels will be the same as someone else's are slim, even though the underlying reality is the same.
