Spiritualist Ectoplasmic Bonded Manifestation shield bonus applys ONLY or ALSO to incorporeal touch attacks?

[~Maxiride]

As stated in the book:

"Ectoplasmic Bonded Manifestation: When a spiritualist
uses this ability and chooses ectoplasmic form, she gains
an ectoplasmic shield that protects her without restricting
her movement or actions. She gains a +4 shield bonus
to Armor Class; this bonus applies to incorporeal touch
attacks."

The last line is a little ambiguous for me, does it mean that the bonus take effect ONLY against incorporeal touch attacks or ALSO against incorporeal touch attacks?

Shield spell:

Shield creates an invisible shield of force that hovers in front of you. It negates magic missile attacks directed at you. The disk also provides a +4 shield bonus to AC. This bonus applies against incorporeal touch attacks, since it is a force effect. The shield has no armor check penalty or arcane spell failure chance.
