Why are people saying returning Pokemon will lose access to certain moves?

For example, Landorus-T is returning in the HOME update later this year, but people say it won’t have stuff like Knock Off and Toxic. Why? I thought home let you bring in any available Pokemon regardless of the moves on it.

Sorry if this is difficult to understand, explaining is not one of my strong points. Thanks in advance!

Here is a direct quote from support.pokemon.com

“The moves a Pokémon can learn may differ between Pokémon Legends: Arceus, Pokémon Brilliant Diamond, Pokémon Shining Pearl, Pokémon Sword, Pokémon Shield, and other Pokémon games. For this reason, if a Pokémon is moved via Pokémon HOME to a game where it cannot learn its current move set, then its move set will be replaced with moves that it is able to learn in the target software.

“Your Pokémon’s move set is saved for each game that you have linked to Pokémon HOME. This means that even if its moves change after being transferred to a game where all or some of its original move set is unavailable, returning that Pokémon to a game it’s been to before will restore the last move set it had prior to being transferred out of it.”
