I would prefer changing the logic too, but that doesn't seem feasible.
Look at this output from another font (ztm-Reg):

Execution completed successfully. Execution completed successfully.
The initial hintmap is wrong, affecting the first set of hints. Because the
(-10,48) pair is not in the first hint group, but is in a blue zone (hence
locked and in the initial map). For Type 1, the interpreter cannot know
this
until later in the charstring when that pair is actually inserted, and
hence
cannot possibly build the correct initial hintmap unless a preliminary pass
is made to collate all the hints.
