I'm not absolutely sure if the following explains that, because none of
the bash man pages I can find describe what those three arguments are,
but:  The zsh bash completions are compatible with bash 2.05b and it is
possible that those three arguments were not passed by that version.

Volunteers to update Completion/bashcompinit?

Based on a quick peek at "compgen" in bashcompinit and a couple of stabs
with "complete -C /bin/echo foo" in bash itself, Thomas is expecting the
external command defined with "complete -C" to receive the same three
arguments that are passed to a shell function with "complete -F".

So the workaround for this particular anomaly is to do

    tu_completer() {
      echo $(tu --get-bash-completion "$@")
    }
    complete -F tu_completer tu
