Reassign and Delete Team - Closed tickets are also processed!

Reassign and Delete Team - Closed tickets are also processed!

Hello,

when I try to delete a team I get the following message:

According to the message, open tickets and open tasks have to be linked to another team or to an agent. 
However, when I perform this action, closed tickets are also processed according to the selected choice - I thought it only affected open tickets... Is this message incorrect?
