If it’s just a monitor or chroma key backdrop why not use a live backdrop? Do they normally use a live backdrop of a different locations - if they do it the change could possibly be because there were issues with the camera or weather made it look bad.
It may not be viable to have a live camera 24/7 on the building opposite, it's a BBC building I seem to recall, but beyond that.......
Also live backdrops can create problems.
Protestors and other 'live incidents outside' spring to mind as being reasons for using pre-recorded footage for the back background that's periodically updated instead of live footage. After all it's hardly ideal if viewers see a car crash in the background whilst on air, followed by the aftermath and ambulances.
