I still don't get that: why do I need to add *twice* ":eval yes", in
both the "inside header args" and the "end header args"?

The documentation [1] states:

  ┌────
  │ END HEADER ARGUMENTS are applied to the calling instance and DO NOT
  │ AFFECT EVALUATION OF THE NAMED CODE BLOCK. They affect how the
  │ results are incorporated into the Org mode buffer and how the call
  │ line is exported.
  └────

If end header args don't affect the evaluation of the name code block,
why do we have to set ":eval" to "yes", then?

                                     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

What's that syntax?  The one described for "header arguments in function
calls"?  Aren't we recursive here: describing syntax equivalent to
a call via the ephemeral code block, reusing syntax for a call?

Not completely yet, no.

Best regards,
