Infinite Scroll appending Next Product Category Term pages

I discovered Infinite Scroll has an updateurl function:

var nextURL;

function updateNextURL( doc ) {
  nextURL = $( doc ).find('.tax-pages a.next').attr('href');
}
// get initial nextURL
updateNextURL( document );

// init Infinite Scroll
var $container = $('#main').infiniteScroll({
  // use function to set custom URLs
  path: function() {
    return nextURL;
  },
      hideNav: ".tax-pages",
    append:  "#main ul.products",
    status: '.page-load-status',
    debug: true

});

// update nextURL on page load
$container.on( 'load.infiniteScroll', function( event, response ) {
  updateNextURL( response );
});
