"In the remaining 48.1% of the sample, the district court declined to adopt either party’s proposed construction."

Based on the above quote from John, I'd say, yes. There is a possibility of a "split decision."

On either of the 2 contested claims we could get part of what we want. Or we could win one claim outright, but have the other left as a partial victory, etc.

Maybe that's what FF had in mind when he said that Markman results were not necessarily an all or nothing event, but that they would impact the amounts we would receive?
