2 official rulings from Bandai, last ruled Mar 28, 2024. Straight answers to how this card actually resolves.

When I use this card's inherited effect to return an opponent's Digimon to its owner's hand, can I gain 1 memory?
No. When you return a Digimon to its owner's hand, the game doesn't treat the digivolution cards as being trashed, so you don't gain 1 memory.

When I use this card's inherited effect to trash the digivolution cards of 2 of my opponent's Digimon at the same time, can I gain 2 memory?
No. Even if you trash the digivolution cards of 2 of your opponent's Digimon at the same time, you can only use this effect to gain 1 memory per turn.
