Did you read the opinion? I did, carefully enough to find; "One final point: police ability to enter the curtilage is not untrammeled; if a homeowner revokes the license with sufficient clarity, police can no longer avail themselves of the implicit license. Of course, police can always enter a home if an emergency or other exigent circumstance has provided sufficient justification to enter. But where no such circumstances exist, police entry into the curtilage turns on the implicit license."
Beyond that, it was obfuscating word salad designed to convey precisely what OPie took away.
