That's because it's garbage and is not coding/decoding. Coding/decoding means there is a 1 to 1 relationship between the ciphertext and the clear text. That means if I give you coded text it will only ever decode to 1 (or maybe a couple if it's a really really sophisticated cipher designed to fake you out) message. Using SB2s "methods" you can take a couple tweets and dates and come up with a bunch of different messages and there's no way to tell which if any is correct. It's a many to many relationship. At each step he makes a choice, and there's usually no particular way to verify it was the right one. It's not decoding, it's more like palm reading or divination. SB2 just sits around all day cherry picking tweets, dates, and names and then playing with different combinations until he finds something he thinks make sense. That's a terrible way to decode things.
