Finally I got the solution of this headache. Actually the Manager group was inheriting from sales / see own leads and sales / see all leads so the result was OR operation of all rules. The problem in my case is driven from the see all leads group's All Orders rule, having this domain filter [(1, '='  1)] which is a special domain filter, allowing all sales orders to show. I just deactive this rule from its document (or if this would be problem for others rules in your case, then simply changed this rule to your desired one), and then everything went fine as I want. This is the domain filter I used in the object sales.order rule of my Manager group [('section_id','=',user.default_section_id.id)] .
