This summary is not the rule. The rule text controls.
If a sheriff has attached property in a case but that property somehow leaves his control before it gets sold, the court can step in and order him to take it back. This might happen if someone tries to move the property, hide it, or take it away from the sheriff before it can be sold.
Once the court gives this order, the sheriff has full authority to go get the property again. He can use the same legal power he had the first time he took the property under the original attachment order. This means he does not need a brand new attachment order to act. He can simply use his existing authority to recover the property so it can be sold as originally planned.
This rule basically closes a loophole. It stops people from dodging a court order by moving or hiding attached property. The sheriff can still do his job and get the property back into his possession for sale.
