This can be handled. Take a look at how gzip(1):


    .TH GZIP 1 local
    .SH NAME
    gzip, gunzip, zcat \- compress or expand files
    .SH SYNOPSIS

I guess something like:

    1. Parse binary names from (.SH) up till (-)
    2. Verify that .IX [if exists] and .TH headers match any of the
       found names.
    3. Likewise, verify that the beginning of the filename matches any
       of the found names.
