This question was migrated from here to Meta Stack Overflow. The author then voluntarily deleted it there, which marked the migration as "rejected" and reversed all effects of the migration (except the part where it was closed as "off-topic").
The question was then re-migrated to Meta Stack Overflow by a different moderator, but that process didn't create a new question there; it instead re-linked it with the (deleted) original migration. The ending effect is that users who click on the migrated question here are redirected to a voluntarily deleted question on the destination site.
Why doesn't re-migrating a question after it was rejected originally create a new question on the destination site? Why did it re-associate it with the original migration that was rejected?

The blue line in the revision history above represents the point in that post's history when the proposed duplicate question was asked; my question is about the items in the history that took place after (above) that blue line.
