CrossRef plugin in 3.2: does Assign DOIs button create new versions?

In the CrossRef XML Export Plugin settings, there’s a button called Assign DOIs that will “[a]ssign DOIs to all published journal objects that have not been assigned DOIs” (see screenshot).

When I use this in 3.2(.1.1) and it assigns DOIs to previously published submissions (eg, uploaded via the QuickSubmit plugin), does it automatically create and publish a new version of the article?

I’m asking because, if I wanted to assign a DOI to a previously published submission manually via the submission metadata, I would need to create a new version first then assign the DOI and publish it.
