using RegisterOnSubmitStatement prevent submit button handler firing

[APA]

Why does adding code to the form submit function using the RegisterOnSubmitStatement method prevent the server side event handler for the submit
button from firing? This is completely useless. I need some custom javascript validation on form submit but why does is kill the submit button event
handler? Submit buttons don't use __doPostBack so what is being effected?

The client script executed by the submission of the form must return true in
order to allow the form to submit. This enables the client-side script to
prevent the submission of the form conditionally.

The problem is when it does return true. When the form does submit it doesn't fire the submit button eventhandler.
