browser=chrome in wptdriver.ini

Searched extensively, but didn't find an answer.

What's the significance of have browser=chrome in the WebPageTest section of wptdriver.ini?

Below is my wptdriver.ini. As can be seen, the machine is hosting 4 browsers, and I want to move away from that. However, I would first like to understand what the chrome browser-specific kvp signifies.
