I don't know the details, but it must have something to do with what
event triggers the reading of the here-document. That event isn't the
execution of the command containing it, I don't think, but more like
when the here-document-redirection is parsed.
This is substantially correct. When the parser goes and collects the body
of the here-document, it's still parsing the contents of the alias.
