By weight the gold recovery is negligible but, depending on their copper buyer, having the ends means they cannot sell the wire as #1 insulated, instead because of the non-copper contaminant on the wire itself, as #2 insulated. Assuming the ends are cut from the VGA cables, this is partially the same answer in that VGA cables tend to have tinned copper that can only be sold as #2 when chopped. They also have a lower copper-to-plastic weight ratio on average - around 40% copper recovery without the ends while cat-5 is a little over 50%.
