Well being a PTZ it can do both, I noticed in their first bulletin in the new set the weather presenter's eyes shifted to her right/back of the tower to begin the forecast.

Remembering of course that rarely are autocues used or needed for weather forecasts.

A look at the Lunchtime bulletin from today shows the presenter standing behind the tower's rostrum and where the tower would be, so I do think the Look East set is slightly narrower than the other installations and a compromise was reached. They also seem to have two PTZs set up, one on the reverse of the tower and one on a ped in the opposite corner of the studio - this may have been a space saving thing.

EDIT: Actually on reflection I think they're using a normal camera for the weather forecast, the wide shot before the throw to the weather presenter on the lunch bulletin was the picture quality of the PTZ cameras seen elsewhere (on the ped) and it increases once they go to the normal shot. The PTZ on the reverse of the tower might be to get the right angle for DTL interviews?
