That is how it works now - the breakouts for the UK will all be 'single story news streams' rather than UK-focused news bulletins. The aim is they are specifically focused on the one story and used across all channels.

They've been fairly good at doing that from the ones I've seen - certainly one aspect of the relaunch that has been better than expected, with some of mine and other's early scepticism about them ageing badly. That said, and while I do understand they are designed as multi-media streams on one story, I do think that when they do run for hours on end or cover live events that are delayed, there is some justification for throwing in a short summary of other news during quiet bits.

BBC "World" were running the Junior Doctors story too with much more panache/presentational flair in some circumstances, while also covering important stories like Biden in Northern Ireland. 

Doesn't the single story news stream concept just mean a smaller team covering the same story with fewer resources? To boot it's alienating viewers that aren't interested in that story at all. Not a good fit for a news channel imo.
