Yes. When you turn the cap to lock it down the locking tabs only turn about 1/16 of a turn. Then the whole bottom of the cap stops turning while the top portion (the part you've got ahold of) continues to turn until it stops. Then you flip the locking lever down.
When you take the cap off you have to be careful that you rotate the top portion all of the way before pulling the cap out of the filler neck. If the bottom isn't turned all of the way to the open position then the cap acts all goofy when you try to reinstall it.
