The parent said “setting” others behind, which refers to lost time.
Being “left” behind implies a degraded trajectory, which is defined not by time lost, but by the final destination.
Different but related things (e.g. lost time can indeed affect your final destination, for instance, after growing old correcting a scourge of hallucinated citations - which should have been table stakes all along).
If all you're genuinely worried about is the collective human time spent on tracing down one stupid hallucinated citation in a paper, may I remind you of the ludicrous amounts of time and effort readers waste trying to wade through the sea fluff, jargon, and complexity frequently added to papers in a completely deliberate fashion. If wasting even a little bit of readers' time is what you see as the crime here, you have orders of magnitude bigger fish to fry.
The fact is that, for one hallucinated citation to be the noteworthy bit that "sets others behind" in any meaningful way, the actual substance of your paper has to be utterly worthless (or worse); otherwise, you're contributing far more than you're taking away, and thus your paper is very much not setting others behind. OTOH, if your paper really is worthless or harmful enough for this part of it to be a big deal, that would be the basis for punishment, not this. A single hallucinated citation is simply not a bleep on that metaphorical radar.
