I imagine everything after BT was the same as it was before, just going into BT was a different source rather than Thames/TVS/TSW/TV-am so a likelihood of technical failure was slim.
You can even see the physical change from sources on the Thames/Carlton handover that's on YouTube youtu.be
Likewise I wonder how long Thames in this case, continued 'broadcasting' the ITN news before knocking it on the head.
Bear in mind video recordings of these handovers are exaggerated - it wouldn't have been that obvious at the time on a TV set.
As to how long Thames kept "broadcasting" - probably no longer than they really had to, wouldn't be surprised if they ceased transmission at one minute past midnight.
There were a couple of videos posted on Twitter/X/whatever its called this week that was recorded on Thames's final night as viewed from the broadcast gallery, but as you can't do anything on X now without signing up, can't look to find them. I can't remember if the output screen was captured after midnight on those videos.
