I can't answer that question. However, by ignoring matter waves, the consequence is to add an unnecessary and unjustified second mystery to the original one. It's also confusing, apparently allowing Schroedinger's cat to be simultaneously alive and dead prior to the "measurement" (when the box is opened).
