The behaviour isn't strange, nor a syntax issue: there is nothing wrong with
your code. The swf simply loops back to the beginning again when it reaches
the last frame - to see this behaviour more clearly, state rotate=240.

To stop the swf from looping you need to place the stop command in your code,
thus,

.frame 51
  .stop
.end

Good question. I'm not sure why.  It works in much the same way though, with
360% == 360 degrees ( which I agree with you, seems a little odd! ) 

HTH.
