You're perhaps confusing myorigin with mydestination.
The myorigin parameter is also not a match list, and so (in the
"upstream" official Postfix releases) does not support indirect
specification via a file.
I am not aware of any "single-valued" parameters that are match lists in
the upstream release. Debian patches Postfix to support an external
file for (IIRC) myhostname, but that's not something that you'll see
otherwise.
