When Matthew was nominating he couldn't think of the name for "Showdown" as he referred to it as the "Saturday games" which is odd since it was filmed on the Friday. I wonder if they've told the HM's that they air them on the Saturday and they must reference "Showdown" as occurring on this day in a further attempt to cover up the 24-hour delay, like when they edited Saturday and Sunday into a single day for last Monday's episode.
I thought the same thing!
It is one thing to starve the viewers of the live and raw house footage (this is what BB thrives on) but another thing to persist with labelling edited footage as live. Also, housemates aren't supposed to know the time, day of the week, etc etc. So if they have been told to refer to it as Saturday Showdown by producers then this is another rule breach.
