[Twisted-Python] Conch - Why does one piece of code "fail" while another works

I have two pieces of code (see: https://gist.github.com/dstufft/9dc9978dc0af77e82f0c) one "works" (in that it fails verifying the host key like i'd expect) and one doesn't ("it never tries to verify the host key and just exists immediately). I don't understand *why* though, why does the connectionReady dance make it work? ----------------- Donald Stufft PGP: 0x6E3CBCE93372DCFA // 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA
