IIRC, questions that were scored as "uncorrected" were those that, even after debriefing, subjects did not identify as swapped.
So if Q1 is scored as uncorrected, part of what happened is that I gave answer A to Q1, it's swapped for B, I explained why I believe B, I was afterwards informed that some answers were swapped and asked whether there were any questions I thought that was true for, even if I didn't volunteer that judgment at the time, and I don't report that this was true of Q1.
If I'm only pretending to have an opinion (B) that's not mine about Q1, the question arises of why I don't at that time say "Oh, yeah, I thought that was the case about Q1, since I actually believe A, but I didn't say anything at the time."

As I say, though, it's certainly possible... I might continue the pretense of believing B.
