This is only saying that they are giving permission, not ordering it to be done, nor ordering others (like family members) to not give food to the patient. There's a difference between the passive giving of permission and the active ordering of others to withhold food and water.

In the end, this Florida court didn't authorize, but ordered Terri's feeding tube removed, and removed the husband from any position of authority or choice in the matter. Following is a quote from the Florida Second District Court of Appeals:
The trial courts decision does not give Mrs. Schiavos legal guardian the option of leaving the life-prolonging procedures in place. No matter who her guardian is, the guardian is required to obey the court order because the court, and not the guardian, had determined the decision that Mrs. Schiavo herself would make.
