A pardon erases prison time, it does not erase any fines resulting from said crime, and also is admitting guilt to the crime[1]. One of the biggest things a pardon does as a result of that (like a guilty plea does as well) is open you up to civil suits. Also, accepting a pardon prevents you from pleading the 5th on any further or follow up charges related to said crime. It is a pretty slippery slope actually. Your question is an interesting one, but one better suited for a Constitutional law scholar such as Professor Lawrence Tribe (runs the constitutional law program at Harvard).

That is the usual interpretation of that case, but not the only one.
