Forum:Uni-horned Familiar Question

I just got a pack in the first time in forever when I received duplicate "Uni-Horned Familiar"s. I thought it was the coolest thing ever until I started reading it. The exact text, word for word is, "When this face-up Defense Position card is selected as an attack target, you can remove from play one monster you control other than this card to remove this card from play..." Now that part is pretty cut and dry. I could use a separate Uni-Horned Familiar for the effect, as long as it isn't the one being attacked. The real question is concerning the third part of the effect, "... During your next Standby Phase, if this card was removed from play by this effect, this card returns to the field." Considering the situation above, (Removing the separate UHF) the attacked one would definitely return if the first part's conditions were compatible, but would the second one remain removed because it was not removed by it's own effect? I would think it would, but after thinking, I'm not too sure.
