Where does it say this? I think you might be confusing one of two sections:

The text alternative computation [1] says presentational elements shouldn't have their host-language labeling mechanism exposed, but that does not include the descendant nodes of the presentational element. Read the long description in the presentation role definition [2] if this is unclear.

The other section you might be referring to is the childrenArePresentational property [3] of roles. This is defined on a per-role basis, and does behave as you describe, but it's not the same as role="presentation" as your text implies.
