Mantelado en Punta on Columbus's Arms

On October 12, 2012, Rodrigo Lopez-Portillo Y Lancaster-Jones posted the following image on the Heraldry Society group page on Facebook labeled as the coat of arms of Columbus & the Dukes of Veragua:

In response to the posted image, Kaj Malachowski asked "why is the "bottom-inescutcheon" upside-down?" to which Xavi Garcia replied: "Kaj Malachowski, this is not a "bottom-inescutcheon" reversed. This is an ordinary called in Spanish "mantelado en punta" and in French "mantelé in pointe".

As I understand it, the english heraldic term would be "tierced in point?"
