I think this is because you are not using EMTERPRETIFY_FILE. This was missing in the wiki docs, I added mention of it now.
Basically, without EMTERPRETIFY_FILE we store the bytecode in the JS file. This is convenient, and fine for small programs, but it is not an efficient way to store binary data. On large projects a file is much better.
