What does "by placing the top card of this Digimon [...] as this Digimon's bottom digivolution card" in this card's inherited effect mean, exactly?
It means that you place the top card of the Digimon with this card in its digivolution cards as the bottom digivolution card. For example, if you have a level 4 Digimon with just this card in its digivolution cards, you place that level 4 Digimon card under this card. This will turn this Digimon into a level 3 Digimon with the level 4 Digimon card as a digivolution card.

This card's inherited effect placed a stacked card under this Digimon's digivolution cards and increased my memory by 2 when another copy of this card was in this card's digivolution cards. Can this be repeated to give me infinite memory?
No, it can't. A record of activation remains for the inherited effect's <Once> even if this card stops being a digivolution card, so it can't be activated twice in the same turn.
