Well, part of the difference is that he denies time as a relevant variable. Even with the BB scenario, to go beyond the very first step, you have to allow for slight perturbations in the density of matter (and energy, etc), which makes the 'absolute space' thing trickier again. So, for example, the existence of gravitational waves in the early universe is very relevant for latter structure formation. But even talking about gravitational waves is tricky if you want to maintain some sort of 'absolute space'.
