One or three?

While reading through Matt Damon Wikipedia entry on the subject of Jimmy Kimmel, I scrolled further down to his Matt’s personal life, where I found the following sentence:

From 2001 to 2003, he dated Odessa Whitmire, a former personal assistant of Billy Bob Thornton and Ben Affleck.

I know, I know all those jokes about Matt and Ben are getting pretty old now.  But still, the question popped up in my head: is it a single person, as in Odessa Whitmire, who used to work as personal assistant for Billy Bob Thornton and Ben Affleck, or are these three different people, as in Odessa Whitmire, Billy Bob Thornton’s personal assistant, and Ben Affleck?

Before anyone assumes anything, I have to say that:

1. I don’t care who dates who – that’s their own business.
2. I have great respect for Matt Daemon, based on many of his movies (I am re-watching the Bourne trilogy at least once a month) and many of his appearances on TV (live shows, talk shows, YouTube interviews, etc).
3. I have great respect for all those people who made the Wikipedia what it is today.

The above quote looked funny to me probably only because I am not a native English speaker.  That’s all.  Enough with disclaimers – you can now tare me apart and flame me into oblivion.
