What does this mean? "Allow vias to connect tracks with no net "

I read the change notes, and started wondering what "Allow vias to connect tracks with no net " might be: Is this something about making new connections in PCBeditor without Schematic editor.

Edit: I think this is obvious, but I just updated from 6.08 to 6.09.

It fixes this issue:

Thank you. Not what I thought it was, I think.
