Contact emails multilingual sends other languages if there is no translation in the current language

Example:

1. Create an email to be sent to the submitter of the form in English and translate it to Dutch.
2. Create an email to be sent to the site editor in English and do not translate it.
3. As a visitor of the site in Dutch, fill in the form
4. Visitor receives email 1 in Dutch
5. Site editor receives email 2 in English

Is the above the expected behaviour or should we make an option when creating an email like 'Send this email if there is no translation regardless of the current language of the submitter of the form'?
