This is a somewhat incorrect understanding, Jean-Pierre.
Once an update is UNapproved/DECLINED on the WSUS server, the next time the
client system executes a detection, it will discover that the update is no
longer approved, and if the update has not yet been installed, it will be
dequeued for installation.

It does, and it will -- but the client cannot possibly know that you've
changed the status of an update on the WSUS Server until the client executes
the detection to find out.
The "missing step" in most of these scenarios, I fear, is that while the
update may have been declined at the server, with the client only executing
detections every 22 hours, and the installation window likely less than 22
hours at the time of detection, unless a manual invocation of 'wuauclt
/detectnow' was executed -- or a GPO change to the detection frequency
(which would have triggered a policy update within 2 hours, immediately
followed by a detection -- thus discovering the approval change) -- merely
changing the approval status had minimal impact on those clients who had
already executed detections and discovered the approval.
