Already provided the link.
My apologies, I missed your link my first time though this thread.
I skimmed through the link you provided and read in detail though the "DISNEY FASTPASS+ Service" section. I didn't see anything that mentioned using the FP+ system would preclude you from using the regular FP system.
Could you please point to the section and bullet that states this.
Thanks.
