Yes you are correct, placing the pick between your index and middle finger allows you to play the fingerstyle intro, then quickly change to the other parts of the song. You could also tuck the pick under the joints of your middle finger. This is what Van Halen does while performing his 2-handed tapping.
Thanks again for bringing this to my attention!!
Keep rocking!!
