Monster Memories

Me and my friends have been advancing in yugioh and now we're at an interesting spot. Monster Memories, essentially cards remembering how they were summoned. So I have a few questions.

1. Frightfur Sabertooth is a Fusion monster that gains immunity to destruction by battle AND card effects if it was summoned with 3 materials. If it was flipped face down and then back up would it remember that it was summoned with 3 materials and keep the effect or just be a sitting duck?

2. Starving venom fusion dragon and many other extra deck monsters get effects from being "Extra deck style-summoned", in this example Starving venom gets an effect to raigeki the opponent's special summoned monsters if it was destroyed whilst fusion summoned, mainly as to not loop the effect. But if it is flipped facedown and then back up would it remember that it was fusion summoned and still have the effect or no?

3. Lastly does the first question extend to other monster types? Reptilianne Melusine is a synchro who if Synchro summoned with only reptile monsters gains the same immunities as Frightfur Sabertooth, would it getting flipped down and up take the effect or nah?
