My guess would be - if I am understanding your description correctly, 
which I am not sure I am - that your firmware (or some EFI binary) 
could be using its El Torito capabilities / methods to achieve access 
to the FAT volume inside your "efiboot.img" file. In there, 
'syslinux.efi' could exist (as it is a FAT volume), but then what?

In the best case scenario, 'syslinux.efi' v.6.03 located inside 
"efiboot.img" could only access something inside / included in the FAT 
volume, and nothing outside of it (meaning, nothing located in the 
ISO9660 volume).

1_ Syslinux as of v.6.03 does not have "multifs" capabilities; it 
cannot access anything outside the volume it is living in.

2_ 'syslinux.efi' as of v.6.03 does not understand ISO9660.


To be clear, I am not saying this is what is actually happening, just a 
possible guess. I could be misunderstanding the case, and, 
independently of my (mis)understanding, my aforementioned guess could 
very well be completely wrong.

Whichever the case, the above points #1 and #2 are valid statements.
