This one doesn't really make sense to me as written: no upgrade is specified for a pawn on the e file, and with the 2‐square slide they can avoid the penultimate rank entirely, which by a literal reading of the rules leaves them as ‘dead wood’ on the last rank. And the significance of the player “decid[ing] whether the move is made orthogonally or diagonally” is also lost on me; that choice would seem to be available at any time.
The specification of “Pawns on the baselines” could be taken to mean that only those on the back rank are subject to upgrading; it's unclear whether this is meant. Presumably the possibility for these to upgrade within a single move is intentional (though opportunities to reasonably forego that option are probably uncommon).
Note that the Interactive Diagram as given diverges substantially from the written description (promotions are automatic without choice on the penultimate rank, and fully unconstrained on the last one), so can't reasonably be used to fill in the gaps in the interpretation.
