Vacation rule for invoice approval delegation. End date should reverse automatic forward

Summary:

After the end of a vacation, the remaining requests for approval or reminding should be sent to its initial approver

Content (required):

John on leave, creates a vacation rule from 1st to 10th of the month and delegates to Tom

The requests for approval are sent but Tom does not approve it all.

John comes back from leave on the 11th but the reminding of transactions not yet approved are still sent to Tom after the 10th for the last few he didn't approve before the end of John's vacation

Is it normal? 

Shouldn't the requests or reminding be sent to John after the end of vacation for the transactions not approved during the leave?
