you set up the trem so that the button slides in between the two plates when your in tune. being that its floating, if you snap a string all the strings go out of tune. the idea is that if you put the button in between the 2 plates it brings you back into tune to finish the song.
I don't find it fiddly - it's also a handy as a midpoint in the trem's travel, a way of having something to navigate back to, trem wise (ie. you adjust spring tension 'til the tremloc works - this means you'll always have some up play and some down play on the trem). Also, it saves a lot of grief when restringing, if you take all the strings off.
Mine doesn't work when I engage the lock, the button is sitting right on the edge of the plate by only 1mm so it just slips out. Maybe a bigger button is needed.
the little screw right below the button adjusts the the spring tention so the plate sits perfectly over the botton if it's slid in or out. I use mine all the time and it helps if you have to tune to drop D or anything like that. just another thing you have to spend a whole 5 minutes setting up to get it to work right
nick in sirens has been using my tele with an avri trem on it,
he asked me the same thing cept i told him it was basically a nice way to garentee that if a string breaks it won't go out of tune.
ever since then he has engaged it everytime he plays it.
