it looks like OrderedSegments in the function is only used to set the physical address to the virtual address when there are no physical addresses set amongst these sections.
I believe this behavior was copied from https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=6ffd79000b45e77b3625143932ffbf781b6aecab (2008-05)

delete a large chunk of code.
