Not sure what you actually want.

If what you wrote is really what you mean, which I _think_ is that all and only the following are allowed

   aaaaab
   aaaab
   aaab
   aab
   ab
   abb
   abbb
   abbbb
   abbbbb
   
then all you need is

  <xs:sequence>
   <xs:element ref="a"/>
   <xs:choice>
    <xs:element ref="b" maxOccurs="5"/>
    <xs:sequence>
     <xs:element ref="a" maxOccurs="4"/>
     <xs:element ref="b"/>
    </xs:sequence>
   </xs:choice>
  </xs:sequence>

If only

 abbbbb
 ab
 aaaaab

are allowed, that can be done as

 <xs:sequence>
   <xs:element ref="a"/>
   <xs:choice>
    <xs:sequence>
     <xs:element ref="b"/>
     <xs:sequence minOccurs="0">
      <xs:element ref="b" maxOccurs="4" minOccurs="4"/>
     </xs:sequence>
    </xs:sequence>
    <xs:sequence>
     <xs:element ref="a" maxOccurs="4" minOccurs="4"/>
     <xs:element ref="b"/>
    </xs:sequence>
   </xs:choice>
  </xs:sequence>
