I often refer back to this link: https://lifefermented.wordpress.com/2013/06/18/brew-tips-cloudy-starsan/
It's perhaps a bit unscientific but reasonably concise, hence why I like it! It says:
1) Starsan is a yeast nutrient in diluted quantities (by which I believe it means a little bit making its way into beer is a good thing rather than diluting per instructions)
2) It kills fungus and bacteria (yeast is part of the fungus family)
It links to a podcast with the makers of the stuff, which might be worth a listen if you're that way inclined.
Hopefully there's something a little more conclusive out there that someone can link to.
