Multiple bioRxiv preprints link to the same journal publication about greenblack

I spot checked a couple:

10483	2016-02-03	10.1101/038729	2016-07-29	10.1534/genetics.116.187369
10155	2017-01-09	10.1101/098095	2016-07-29	10.1534/genetics.116.187369

Looks like it might be folks uploading revisions...

I can envision a situation where multiple preprints end up being published in the same journal article. For example, perhaps two preprints were combined into a single work that was then published in a journal. Or as @cgreene mentions:

Looks like it might be folks uploading revisions...

I've gone through a few more:

• https://doi.org/10.1101/156331 and https://doi.org/10.1101/165373 both are marked as now published in https://doi.org/10.1007/s00401-017-1789-4. I am not sure about this one.

• https://doi.org/10.1101/008755 and https://doi.org/10.1101/046995 both published in https://doi.org/10.1016/j.ajhg.2015.03.004. I am not sure about this one.

• https://doi.org/10.1101/125419 and https://doi.org/10.1101/253872
  both published in https://doi.org/10.7554/elife.3487. Looks like revisions.

• https://doi.org/10.1101/122580 and https://doi.org/10.1101/125765 in https://doi.org/10.7554/elife.27356. Looks like revisions

I thought I initially found one where it did not seem like the preprints should both be associated to the same journal publication... although given that many of these don't seem to be errors, I am not too worried.

This one is really odd. The number of authors dropped with the later preprint but went back up for the journal (if it's a revision):
https://doi.org/10.1101/008755 and https://doi.org/10.1101/046995 both published in https://doi.org/10.1016/j.ajhg.2015.03.004. I am not sure about this one.

In any case, I agree with you that it doesn't seem like a big deal.

Playing with #Rxivist database and noticed instances where multiple #preprints were marked as published by the same journal article.
Many seem like revisions posted as new preprints or other corner cases. 
@biorxivpreprint, how do publications get matched?
