It's very unlikely that the Old Dragonslayer in Heide's is the real Ornstein. More likely he's either a soldier who took up Ornstein's armor and title, or it's an illusion/golem designed after Ornstein.

The Royal Sentinels of Anor Londo seemed to be little more than golems themselves, which makes it highly unlikely that they had minds of their own, much less the willpower to rebel against Anor Londo. If Heide's is truly where Gwynevere and the other gods went it's much more probable that they simply took some soldiers from Anor Londo with them, or created new ones at Heide's.

As for the Dragonrider's presence; he was likely sent there to secure Heide's by either Vendrick or Nashandra for their own purposes.
