Makes no sense. Think about it. Say you want to fish five feet deep so you put a 1/2 ounce weight at 4 1/2 feet down to keep your bait low. You could throw that out in 100 foot of water. If it floats to the bank in less than four feet is it suddenly illegal? No. Free floating has to mean you can grab it and move it without having to untie it.
That's my interpretation of it any way.
