Yeah I noticed that immediately, that's what spoilt it for me, really.

I have tried to explain this a fair few times, but it seems really hard for some people to grast so here it comes again:

if you derail the chain off the chain ring it will slacken significantly and you can remove the rear wheel without breaking the chain.

I didn't believe it at first either, but I have tried it and it works!
feel free to try it yourself if you're not yet convinced.

Thanks for explaining that, dron, I was being sarcastic. I was going to explain it myself but I didnt want to sound like, well, to sound like you just did...
