Yup, you need to redefine the ID as well with -sid Q12345

The id is the identifier on the ID line of the entry.

The accession number is from the AC line - also a unique identifier but
completely unmemorable. Given the choice, we prefer the real ID. Entries
can also have more than one accession number (more common for EMBL entries
than for UniProt) where entries are merged or changed.

entret will show you the full entry so you can see where the identifiers
come from.

Hope that helps,

Peter
