Two dancers?

I read the plot summary of the film and it claims it features two dancers.
The film I watched on the Internet with this title only has one dancer in it.
Did I watch the right film and the plot summary is wrong or I watched something else that was given the wrong title?

I am under the impression that the summary talks about two different films, the earlier Annabelle Butterfly Dance (1894) wich I also saw on Youtube and this one, and that it mistakenly considers them to be part of the same picture, but I wanted to check before making any corrections.

I want the daily poll at the IMDB.
