I must admit I did wonder about the rescue element too. All the rescues I've dealt with make it a condition of contract that dogs are kept indoors, and if they found out a dog was being kept in this way they would reclaim it immediately.
Obviously rescues do their best to check prospective homes, but people can be dishonest and very convincing about things like working hours, for instance. It's part of the reason The Oldies Club always do follow-up checks as well as pre-homing visits so we can see that all is well, but some smaller rescues simply don't have the volunteers or resources to do this.
Some people also rescue directly from council pounds, and in those cases it's often just a matter of handing over the money and taking the dog with no assessment or checks of any kind (though not always - some pounds work really hard to home responsibly).
