He means if you had an image misnamed say "Mr Kermit Vol 3 1" and it should have been "Mr Kermit Vol 2 1" and you left the redirect behind when you renamed it, then when it came time to add the real "Mr Kermit Vol 3 1" you had to go hunting for a bunch of redirects to fix 'cause someone was too lazy to do it when they renamed it and instead just left a redirect behind.
