Well, for starters HelenAngel is not confirming that all blocks are being moved/joined. Albeit she is saying implying that most blocks will need to be moved in order for cross play to exist.

She also says that for example they are working on ravines, but it's not guaranteed that it'll make it into 1.2, and that it is world generation and as such don't need to be added in order for cross play to exist.

In short, the only thing which is guaranteed is that cross play will become part of the Better Together Update. Which actually blocks or game mechanics or generated structures are added, remains to be seen. Claiming they are confirmed is at best educated guesses.

Even Helen uses the term "pseudo-confirmed" on a related chat: https://cdn.discordapp.com/attachments/279745300640301077/324258466283782144/image.png
