The smali code that is generated is in fact reassembleable. The smali format is meant to be as close to a 1-to-1 mapping for the dex file as possible. Disassembling and then immediately reassembling something will produce an equivalent (almost identical) dex file. The only things that might be different are misc. internal details, like the order of certain items, etc.
