I believe, correct would be:

The test for pform != form is wrong anyway.
Next one has to care for Post-gap: table 555 in mmc5r03c.pdf does not
show any although 6.33.3.19 would prescribe some.
Nobody seems to have ever tested this situation, up to now.
I shall ban resp. avoid it in cdrskin and libburner. A warning will be
placed in libburn.h . Some ban is needed in burn_disc_write().
