A long time ago, I asked this question under my old account. It has a score of 0 (but for a long time had a score of 1 with a deleted owner), has no answers, is not locked, has a low view count, and has zero comments. It therefore meets the criteria for deletion according to this. But it's not deleted.
After doing further research, I found that the original change (by Jeff Atwood) to add one of the auto-deletion criteria explicitly excluded meta sites. It's not mentioned in the answer, neither is it mentioned in the help page, but according to the question such questions aren't automatically deleted on meta sites:
Every site in the network (except metas) will automatically delete old questions that meet this criteria from this point forward.
Why were meta sites exempted from this rule? Should they be exempt?
Also, if meta sites were excluded from parts of the criteria, specifically the part under which the above question meets it, why does the MSE help page say that such questions are indeed deleted, even if they're not?
Finally, does this apply only to the
RemoveAbandonedQuestions criterion, or does it apply to any other criteria as well?
