"Import into Photos" with a Referenced Photos library

Hi,
Just looking for a bit of background info / clarification - if I use Photos.app in referenced library mode, does the the "Import Into Photos" action play nice with that? As in, does it cause a reference to the image to be added to Photos, leaving the file itself in its place?
Thanks.
