ADN8831 Driving >4A

The ADN8831 eval board app note, AN-695, say it's designed for "medium power TECs (<4A current)". 

This part controls temperature by controlling voltage on an H-Bridge.  As long as we use transistors don't overheat (based on their R[DS,on] and thermal resistance), why does the ADN8831 care how much current goes through the TEC?
