No, as the SEH metadata is defined in the .text section just like the
preceding code, there should be no functional difference between them
on x86_64. As far as I can tell, this is largely a matter of style -
for example, LLVM does not appear to reference .seh_code anywhere in
its codebase.

The latest proposed AArch64 SEH implementation in binutils does not
support the .seh_code directive at this stage.

As for the original reason for the introduction of this directive,
the binutils commit 3c6256d29e2c528880a3cf8df43adf32c7780de5 from
2014-03-25 by Nick Clifton <nickc@redhat.com> explicitly states:

So it seems to have been initially used for convenience.
