yes that's what I understand too

yes I think it's safe to remove the check; pm_SecPerTrack is unused anyway.
There's a comment on this in FreeBSD:

        /*
        * We don't check pm_Heads nor pm_SecPerTrack, because
        * these may not be set for EFI file systems. We don't
        * use these anyway, so we're unaffected if they are
        * invalid.
        */
