Did bipedalism develop before hominids were in the "mosaic savanna ?"

So the early signs of bipedalism were enhanced in the savanna ?
Could someone explain how the "mosaic" in the "mosaic savanna" explains
in bipedalism that simple savanna doesn't. Perhaps grassland instead
of savanna might be more appropriate. In trying to visualize this,
did the hominids already live in the dense forest (with early signs
of bipedalism) and then as the dense forest changed into savanna, early
bipedalism helped in predation/escape and ultimately evolved to its
present stage (?). Hmm, perhaps when looked at the evolving system
as a whole, less energy went into the system (at least all man
had to do was simply stay where he was :) to create bipedalism than
migrating to the sea/coast. Thermodynamist, does that make sense ? :-).
