Codex:

Processes the directives on the rendered HTML of the interactive blocks.

This processes only one root interactive block at a time because the rendered HTML of that block contains the rendered HTML of all its inner blocks, including any interactive block. It does so by ignoring all the interactive inner blocks until the root interactive block is processed.
