[Tango-L] Milonga sequence

[Richard Lipkin]

Here is a clip from the Argentine film "La voz de mi ciudad" with Mariano
Mores and orquesta playing Taquito Militar.
There is a seven second dance sequence at 2:53 which is performed in such a
different way.

Can anyone explain it? Is it merely a film choreography of no great
historical value? or is it an example of an obscure or forgotten style?
