Not if he removed I think Aaron only replaces non-working lamps even in a group replacement. Sometimes they'll keep working after they've leaked but they won't be bright.
It probably would have been on it's last legs anyway as it was slightly leaking. It's cheaper to have them replace the lamp now then to call them back in a couple months just to relamp this lamp.
Group relamps make sense with MH but fluorescent not so much, life is unpredictable and I'd say they could wait longer than 3-5 years to relamp! The F32T8/25W/SPX41 lamps have a life of 50,000 hrs
Might be good for a NST experiment though.
