Approval notification visibility regarding Approval delegation to another user

For PPM modules, we are creating approval workflows (ProjectStatusNotificationApproval, ApprovePlanVersion, ContractsApproval) using approval groups in BPM. After we set up the approval groups and assign users in the groups, we are now testing delegating vs reassigning for these approval flows.

My understanding is:-

When user 1 "reassigns" an approval task to user 2, only user 2 can receive the approval request notification and can approve it, since the workflow has been transferred to user 2 completely via reassigning.
When user 1 "delegates" an approval task to user 2, both user 1 and 2 will be able to see the approval request notification and both can approve.

1. Is my understanding correct?
