Reassign and Delegate Approval tasks within Approval Groups

Could you please confirm that, when dealing with Approval Rules using Approval Groups, there is no difference between Delegate and Reassign? For instance, if we have two approval groups "AG1" and "AG2" composed with two users each, like as follows:

if G1X reassigns a PO approval task to G2X, who approves, then the approval is still routed to to G1Y (as in Delegate case would happen), instead of being routed to G2Y, as the definition of Reassign requires?

Thank you,
