Post-2007 Federer was rarely at his best for non-Slams/WTF, which explains the H2H. Even at their respective ages, I'd still expect Federer to win most of their Slam meetings, although his decreased recovery powers might throw a spanner in the works (ie if he plays a five setter before facing Murray his task will be much harder).
At the AO match Murray was actually out-hitting and overpowering Federer off the ground for long periods of the match. Of course, Andy's offensive ground game has improved immensely, but the Federer of old wouldn't be getting bullied by him, which is a sign of his decline really.
