Why did the voyager have to lose its bonus feats? Those were flavorful combat ribbons.

Rewind (3rd level):
The voyager can use her parallel turn to pull herself back to an afterimage of herself, teleporting herself from her current location to her afterimage. As an immediate action, the voyager can expend her psionic focus in order to immediately return to her afterimage. Doing so in response to an attack or ability grants her a bonus equal to 1 + 1/3 of her class level to her AC and on saving throws against the attack or ability. A successful hit or a failed save means that she teleported too late and was affected normally. Using this parallel action preserves the voyager’s momentum; at the beginning of the voyager’s next turn, she does not lose any gathered points of momentum."

Wait a minute; how is this an immediate action if this is a parallel action? Does a voyager have to dedicate both their parallel action and an immediate action to this? Can you use it as a parallel action or an immediate action?
