Yeah, this is how I have drank mate my entire life and everyone I know (apart from my wife and her Uruguayan family) drinks mate in this way. I'm originally from Bs As, but I've confirmed this with folks from Salta (NW), Santa Cruz (S), Corrientes (NE, althought not as much as Formosa!) and the odd Cordobes and Mendocino as well.

Uruguayans tend to be more likely to have one thermo and mate per person, similar to the tradition in Corrientes (which makes sense if you look at who their immediate neighbors on their western border are).
