In the document that you provide the author is doing something outside of the norm and accessing the block data directly so he is calling these function in the same way that ACF calls these function. He is looping through the blocks on the page, calling the acf_setup_meta() function and then calling acf_get_fields() in order to store all the ACF fields for a specific post into an array that can be used later.
