I think he's referring to the "architecture-specific" tags (which are
currently not fleshed out in the spec). There are different sections for
x86 and x86-64, and it is a good question about when each is used.
I'm really not sure what would be different about the two sets, but if
there are differences, the ELF class seems like a reasonable way to
decide which to use.
