They almost certainly will be named to indicate when they are for - each organisation has a naming convention for their staff to name clips on their servers so it's obvious what everything is. They'll also have a deletion/archive policy to remove old material and make room for new content. So stuff will stay on server for x number of days before being removed or archived offline. Usually these days it's done partly or totally automatically, looking after all that is what a Media Manager does
As to how that could happen given all the above. Well quite easily as it's humans (journalists, DJs, producers) who put things in play lists and who create the audio clips. So either the wrong bulletin was dragged into the running order or somehow the wrong audio was saved onto the playout system with the correct name.
Never underestimate the amount of a muddle a journalist can get with saving into a server, creating clip names and dragging in MOS objects. I worked as a media manager for years the classic was producers publishing a clip with the same name as the source material (why I don't know) and the system deleting the source in the process (yes the system didn't have a failsafe for that), or making the same item with lots of different names - which one to play, which to archive? In the 00s the naming convention suddenly changed in the second week of September so whereas the convention for the date was <day>_<month>_<year> they'd suddenly publish stories called 911_PKG_09_11_15 they weren't for November
