As I understand it, if you have the first, the second follows from it. So it's effectively the same.

Not the same at all. Free as in beer means you get nothing. Free as in speech allows you to get as much money as you can using a threshold pledge system. This isn't just theoretical: the famous 3D modelling software Blender was released this way, becoming Free Software only after a €100,000 payment.
