I don't have access to your sample solution which contains the issue but i encounter a double postback too in my project with the AsyncFileUpload component. I found a very simple workaround :

Just add:

private bool justUploaded = false;

Then:

void AsyncFileUpload1_UploadedComplete(object sender, AsyncFileUploadEventArgs e)
{
    if (justUploaded) return;
    justUploaded = true;
    // rest of your upload code
}
