Agreed it's a mess, and I don't know why anyone would do it, but
that's only part of the story. I don't think the OP was wondering
where the 1s came from; at least I'm not. I am wondering why it
displays:
toctoc hihi u 1pupu zozo 1v 1tata 1coucou 1
instead of
toctoc u 1hihi v 1pupu zozo 1coucou 1tata 1
