Notice the exact form of the above (IIRC that was my suggestion).

Whoever said that does not know what they are talking about. With
the default of "append_dot_mydomain = yes", Postfix will replace
"user@localhost" with "user@localhost.$mydomain" before performing
recursive lookups with virtual_alias_maps.

No, that can't be done literally, one would have to replace
"$mydomain" with the actual value. To quote Dr. Seuss: I meant
what I said and I said what I meant.

The ".invalid" TLD is IANA reserved for invalid domain names.
If these aliases are to be effective the RHS needs to be in a valid
domain, your choices are "localhost" or "example.com". The former
will perform local(8) delivery directly without generating a new
queued message with the expanded recipients. The latter will do
indirect (new queue file) delivery because example.com is not in
mydestination.

Never leave RHS domain unset in virtual_alias_maps. Replace the
RHS with postmaster@localhost (which punts the mail to local(8)
for aliases(5) expansion) or with the full addresses of users
receiving postmaster mail. The LHS can only be left unqualified
if the virtual alias domain is equal to $myorigin. Otherwise,
it too MUST be an FQDN.
Thus, either:
# Actual expansion in local(8) aliases(5). Not recommended.
#
postmas...@example.com postmaster@localhost
or:
# Actual expansion in local(8) aliases(5). Preferred:
#
postmas...@example.com us...@example.com, us...@example.com, ...

Same as postmaster!

Use virtual(5) for ALL address -> address mappings, with only
addresses that represent final mailboxes listed as account@localhost.
Use aliases(5) sparingly, only for "|command" aliases (try to avoid
these anyway) or ":include:" lists.
The aliases(5) file is a Sendmail compatibility feature, whose
features are best remapped onto virtual(5) (address to address
mappings controlled by the administrator) and .forward files (own
address to address or command mappings possibly controlled by shell
users).
