This ruling is a bit illogical for me. I explain.
I play an aid from the bat, but my opponent play Immortal grapple. At strike resolution, I can't play the Aid, so I have no strike.
I play an aid from the bat, but my opponent play Withering strike with first strike. At strike resolution, my Aid from the bat is resolved anyway.
In a pure logical sense, I must admit having an hard time to see this as making sense. (also, it screw further first strike, which is already not the sexiest effect on earth)
Withering allows you to declare strikes. Immortal Grapple forbids some strike declaration.
See also: You can play Burning Wrath with Immortal Grapple or Withering. It has nothing to do with the fact that Burning Wrath / Aid from Bats requires a discipline. What matters is when the effects of a card apply.
For non-strike (and non-action) cards, they resolve as the card is played.
For strike cards, the strike is resolved during the strike resolution, which happens after the strike declaration.
Immortal Grapple affects strike declaration. Withering doesn't.
Why is it illogical that two cards with different texts have different effects?
