Probably because the plasmolysis will show up the mitochondria better.
I wonder whether that's still true when using phase contrast.

and what is the role of janus green B in this experiment?

It's a basic stain. Don't know exactly the pH of a mitochondrium, but
they dissolve in acid fixatives, so I guess...
