Your are making a distinction between " Styles " : its the SAME dance, but,stylistically and technically, the 2 are quite different .
Many variations in salsa, at a basic level, are pretty much the same, no matter the style ( Cali and Cuban ,are different, as can be the music ).
And, I would agree with you , that the BR style ,looks very out of place in an authentic Latino club . States-side, B.R. types, are very rare in the Latin clubs .
