Well the big question is was Doc duplicated?
We know that this doc (which ended up in 1885 with that delorean) eventually went to 2025 to retreive it, so did that delorean end up in mid air in 2025 without a driver? Unless something happened to him I don't think there was a duplicate doc. If there was he wouldnt know he was duplicated so you'd think 2025 doc would go back to 1955 for Marty (since he had the technology to fix the delorean).
Also the time circuits in part II were flashing January 1st 1885 twice on screen (once right before they go back to 1955 and once when doc flies the delorean to the school). Now granted these are the only 2 times we are seeing the time circuits after they leave 2015, no reason they couldnt flash 2025. Or you could argue that the combination of the jiggowat overload, scrambled time circuits, and spinning delorean confused it as to whether it should be going to the future or past (logically it should have to perform an internal calculation for how far it needs to travel and whether its forwards or backwards)
