You didn't, but made an error in how SQL object names work:

> ➜  ~ psql -U julien -W -p 5432 -d postgres  -c "create schema schemaA; create schema schemaB;"

this creates schemaa and schemab, not schemaA and schemaB.  If you want objects
to be case sensitive at the SQL level, you need to double quote identifiers,
like "schemaB".

> ➜  ~ pg_restore -p 5432 -W -d postgres --verbose  -N schemaB dump.sql

this on the other hand is a command line utility, and will use the given case
(and properly quote identifers at the SQL leve), so it means "schemaB" which
isn't found and thus not filtered.
