Now I think I understand what is happening.

You must have the YNU set to a fairly low power, so that it fires on the preflash, and it is recycling just enough to fire again on the main flash. I think you will find that if you shorten the shutter, and/or increase the power of the YNU, it will fire on the preflash, but will not have time to recycle, so it will not flash again on the main flash.
