Well as long as they use the 3 comma and 1 comma versions, both of which can claim some degree of being official, I suppose that's OK.
But you'd have thought they'd have chosen one and then stuck with it.
But I checked, and they didn't. Instead, in their second use, they used a two comma version, which has no historical basis, AFAIK.
That just goes to show that commas or the lack thereof, are about as likely to be typos, or the hand copying equivalent thereof.
