Providing too much information will weigh against candidates, sure. Filtering information to what is relevant is a very useful skill: it saves time, helps listeners focus by not overwhelming their working memory, and lets the speaker communicate clearly with show-not-tell.
Saying something that is untrue is completely different from blurring or glossing over some of the details. The interviewer can always ask follow up questions if they want to hear more details: lying removes the opportunity for accurate understanding.
Saying something that is untrue might sometimes help someone fraudulently land a job: if it is believable, if they can back it up when asked, if the company never finds a way to check and if they never contradict themselves at all.
But it is just as likely that the answer "I don't have any experience with that, but I would google '<phrase>' and start from there" would have done a better job with no possibility of being summarily and appropriately dismissed if they get caught.
