Yes, I guess it might be counter-intuitive but the tyLooper modifier doesn't loop the animation per se, but just gives you a loopable deformation. You'll need to loop the animation yourself. The easiest way is to put a Point Cache modifier on top, then use the playback graph mode to define start/end keyframes, and then set the playback graph controller to loop (you can do this with the out-of-range types control from the Graph Editor...just set to loop)
