No, that is how it works. As a 'controller' it should only issue
the 'pre-flash', which as the name implies, is fired BEFORE
the shutter is open ...

That is hard to detect though, you can only see it in
the images (if the flash is reflected for instance) or
perhaps in very long exposures (1 sec or so) but
I did not test that ...
