Looking at it from the other player's side, you can see the effectiveness of it (the playback here by the bigger stack with the presence of the super-short stack). Good to have in the arsenal to be applied at the appropriate time...

...I wouldn't have done it as the button with Q5 (he's barely got you covered, and he will get called by a player in your spot a good % of the time), but as the SB, I think it would have been a great play, since losing means you still have the short-stack way outchipped, and you're tied for 2nd if you lose.
