According to Wikipedia, CS4 came out in 2008, when ePub was in its infancy - which was out for about a year or so (2007) and e-Ink devices were just rearing in their ugly little sluggish heads.
On the other hand, CS5 came out in 2010 and CS5.5 in 2011. That's something like 2 - 3.5 years advantage. Chances are they cleaned it up.
