What I got from that paper is that it was (or could be) present, but they did a bunch of statistical analyses on the data in an attempt to show that it couldn't actually account for the results they obtained.
A better approach, in my opinion, would be to come up with an experiment that rules out expectancy effect
by design. While possibly more difficult to do, this would be much more compelling than trying to rule it out by doing a bunch of fancy number shuffling around some assumptions about how it may or may not affect the data.
