I've attached a vtt file for you with two "regions". The cues should
each get limited to their "region".

You can see for yourself how this breaks down with 2 regions present.

I think it's quite clear that the concept of cue groups codified in
regions is a more appropriate approach than building ad-hoc groups of
captions by trying to group them based on them overlapping each other.
