Seems this issue has been around since Watch OS 2.1 or even before.
Have a group message, with about 9 people. 4 of them are not using iPhones, they are on android, so it is an SMS message that is sent. When I get a text from the group, in the group message, and select on my iPhone, HIDE ALERTS, this rule is not obeyed on my apple watch with WatchOS 4. I still get alerts on the watch. This is when I have "mirror iPhone" set for messages on the watch.

Not sure if this is a bug, or if there is a reason this happens,
