Content Status Table Publish Update

Whenever, we execute an edition, after editing content items, and switching them to Public state, there is a delivery of those items.

I have few questions on this:
First, does this results into creation of a new row, or it updates existing row for the content item.
Secondly, does it updates the contentpublishdate column as well?

Just fyi, I did the following steps:
I ran the edition for Corporate investments after making changes to some content items, and changing their state back to Public. I see them delivered on seeing the logs. However, when I go an look into ContentStatus table, I dont see any extra row created. When I open the existing row for the content item, there is nothing in content publish date column.
