I think that means you can keep using the disc until the director says it is illegal, but you are assuming the risk of taking penalty throws or even being disqualified if the director subsequently rules the disc illegal.
My reading would be that you can't use it. "Until" would imply that the disc will
be approved by the TD; "unless" that it may or may not be.
