It seems like the other accelerators are doing this so they don't end up with only YC-rejects. Since YC is probably considered the top accelerator, it's also better for YC to have other accelerators not give exploding offers. Because then the few companies that would have accepted the exploding offers AND also would have gotten into YC, can now actually go to YC instead of accepting an exploding offer. If I missed something, I'm sure you'll point it out ;)
