The Pill interferes with caffeine absorption?

I was perusing this site (http://womenshealth.about.com/gi/dynamic/offsite.htm?site=http%3A%2F%2Fwww.uiuc.edu%2Fdepartments%2Fmckinley%2Fhealth-info%2Fsexual%2Fbirthcon%2Foral-dru.html), where a list of possible interactions of medications with oral contraceptives are listed. Some I knew about, such as penicillins and tetracyclines interfering with the Pill’s effectiveness.

What surprised me was this:

Ehhh? Anyone hear this one before? How does this work? And, as someone on OCs with a regular coffee habit, how can I take care of myself? (I have noticed that if I’m not careful, I can overdose; I just always blamed the coffee, thinking it was too strong.) Should I not drink coffee (well, at least the caffeinated form) at all? (Please no!)

This was news to me. Looking for anyone’s knowledge on the subject here…
