To be honest, I just think they cropped the 4:3 titles to 16:9, and they wouldn't have been the only show to do that. The 1998 Emmerdale titles lasted longer cropped to 16:9 than they did in their original 4:3.
They were showing widescreen episodes of Price is Right, which allows me to bring up the geeky point that they used the same opening titles they'd been using since series 2 when they went widescreen, so must have had to go back to the original design company that made them and re-render them in 16:9.
