The $index argument seems to be NULL for append operations, e.g.:
<?php
// example extension class
class Test extends ArrayIterator
{
 public function offsetSet($index, $newval)
 {
 echo 'Test::offsetSet('.var_export($index, true).', '.var_export($newval, true).")\n";
 }
}
// test
$i = new Test;
$i[] = 'append a value';
?>

The result is:
Test::offsetSet(NULL, 'append a value')
