Can I assume that the left-hand side is the last job in the table
(this seems to be the case in all the tests I've done)?

That would be nice as a precise status is provided: either "running"
or the exit status. And this would be very useful as it appears that
$pipestatus no longer contains the expected value if the jobs builtin
is used:

zira% false | { sleep 1; jobs } ; echo $pipestatus
[1]    exit 1     false
0

i.e. "0" instead of "1 0". Is this a bug? At least, this is not
documented.
