Maybe the typed info is older information, like previous scores and comments from the judges, reference to things they said in their VT, and the all important phone numbers; and she has one card for each couple?
And when she's looking at the card, 'reading' what the judges have said, she's actually being fed the comments through her ear-piece and the 'reading' is an act so she isn't staring into mid-air/blankly at the couple as she listens to the producer.
Or maybe she's remembered what the judges have said, and just looking over what she's going to say next re. VT comments / previous scores/ phone numbers etc.
