What 'order'? All their report says is 'request'. If they had meant order, they would have said court order: in all the other cases in the transparency report, they specify if there was a court order.
How does that change the fact that saying "I tweeted it so it's true" is not a strong argument in a he-said-she-said debate?
Which do you trust more, a witness statement taken a minute after the crime, or made a year later?
That someone said something very revealing and immediately backtracked with an excuse "I didn't say what I said" is, on the other hand, deeply unconvincing.
