Some of their processes may have changed since this video was made - I had one padded envelope returned to me marked as an incomplete address, because I put CR (as in for example 100 Made-Up CR, [Suburb]) when I wrote the address. Everything else about the address was 100% accurate, but somehow either a person or the system couldn't determine if it was court or corner so it was rejected. A person shoud have been able to determine that it was indeed corner by the rest of the address, a (badly programmed) machine probably wouldn't, so it could well have been machine sorted in some way.
