Description lines used in Adwords matching

Broad match?

I came across a SERP page that appears to show that description lines are used to match Adwords ads with search queries.

I'm assuming that Broad Match is matching the query with the description lines text.

Can anyone confirm this?

Thanks

Sorry - nevermind me. I've been nibbling on my tin foil hat.
