jQuery Grid Plugin - jqGrid

I believe this might be a bug:  the loadComplete event is firing on all sort and paginate clicks, when the documentation seems to suggest that it shouldn't--it says that the gridComplete will fire on sorts, paginates, etc., but the loadComplete says "This event is executed immediately after every server request."  If I set the script to use the "loadonce" feature, it seems as though the loadComplete should NOT fire on sorts, paginates, etc--just ONCE after the initial load from the server.  

Am I reading this wrong?  Or is this actually a bug?

The code that I think is relevant is pasted below.  I've tried 3.7.2 and beta 3.8.  

jQuery("#list3").jqGrid({

   url:'ajax_server.asp',

datatype: "xml",

   colNames:['','Column1','Column2'],

   colModel:[

   {name:'Column1',index:'Column1',sortable:true,sorttype:'int'},

   {name:'Column2',index:'Column2',sortable:true, sorttype:'text'},

   ],

rowNum:10000,

viewrecords: true,

loadonce: true,

loadComplete: function(){

alert('init loadComplete');

},

caption: "my grid"

});
