Thanks for taking the time to point out the problem with each example.

The key issue seems to be that "subjective experience" could refer to all subjective experiences, both past and present, or it could refer to one's current, this-moment subjective experience. The OP draws people in because it sounds like it's going to be talking about doubting the latter - which would be pretty shocking - but it ends up as a sort of bait-and-switch because it is really talking about doubting the former, more mundane and familiar sense, where one simply fails to accurately recall one's past experience or fails to catch all aspects of one's experiential phenomena as they whizz by.
