Whether or not it's "right", the format does not give you the option.
The token system defined in the specification has two ways of exploiting
runs: runs of zeros _within_ a single block, and runs of EOB tokens
_across_ multiple blocks. You can't code runs of zeros which span
blocks, except through EOB tokens.
