Why would you need a fall back role? As this completely changes the users expectation of the control. If something is a button it is a button.

The technique is valid to provide a fallback role, but the second role is not a suitable fallback for the first in this example. I don't think that will affect accessibility, though, because buttons are supported everywhere AFAIK.
