Is it expected that multiple delegations for approvals would send to the last that was delegated?

Summary:

My client has delegations done by multiple people. What is happening if the delegated to person also has delegated their approvals, there is a cascading effect of their delegations so that it ends up with the last person in the delegation list.

Content (please ensure you mask any confidential information):

For example, the Chancellor delegates to the Vice Chancellor who delegates to the Associate Chancellor who delegates to a Director. The Director is the one that is receiving the approval notification.

The expectations of the client is that it should stop at the first delegation.
