How do I call the Magento API SOAP V2 with multiple complex filters to the same field?

Since the Magento community in StackExchange seems to be dead (at least for version 1.x), I ask my question here. I hope you can help me. After all, it's a 'problem' of the Magento API. ;-)

How do I call the Magento API SOAP V2 with multiple complex filters to the same field?
In my case I use the salesOrderList function.

This source code does not work:

$params = array(array(
        'complex_filter' => array(
            array(
                'key' => 'increment_id',
                'value' => array(
                    'key' => 'nlike',
                    'value' => 'a_%'
                ),
            ),
            array(
                'key' => 'increment_id',
                'value' => array(
                    'key' => 'nlike',
                    'value' => 'e_%'
                ),
            ),
        )
    ));

$result = $client->__call('salesOrderList', $params);`

The final sql code only contains:
AND (increment_id NOT LIKE 'a_%')

But it should contain:
AND (increment_id NOT LIKE 'a_%') AND (increment_id NOT LIKE 'e_%')

For SQL it doesn't matter how many 'LIKE's I apply to a field?!!

What am I doing wrong?

Seems like a reasonable expectation. Pull requests are welcome. :)
