Theory: (Destiny)

In some prior-to-release version of the raid, Oracles would fire these (tracking) orbs at players to mark them for death (after the Oracle remained alive for a certain amount of time). Perhaps whatever tracking algorithm used for the orbs was deemed too buggy, and the marking mechanic was changed to be instantaneous. The orb triggering mechanic was "suppressed", but due to subsequent changes and tweaks the orbs are still able to spawn when certain rare conditions are met.
