$this->email->clear(); not clearing attachment???

[eluser]nevsie[/eluser]
I have two emails to send on completing a long form... one to business one to customer.
After setting up the first i then call the email clear function, and run through the next, as below...
But for some reason the attachment does not clear, and send with the second email too...

Am i missing something obvious or is this a bug?

Code:

$this->email->clear();
$this->email->from($email, $name);
$this->email->to('[email protected]');
$this->email->subject('Enquiry');
$this->email->attach($file['full_path']);
$this->email->message('Message text would be here...');

$this->email->clear();
$this->email->from('[email protected]', 'Company');
$this->email->to($email);
$this->email->subject('Enquiry');
$this->email->message('Message text would be here...');
