Multiple Taxonomy terms - AND not OR

Hi,

Before I post the question, Let me clarify that I have searched extensively - infact have been researching for the last 2 days and all the possible solutions I found seem to be from 2007 and even those were for views 1 and not for views 2

Now the Question

I have overriden the default drupal taxomomy/term page with the views provided taxonomy/term page.
taxonomy/term/x or taxonomy/term/y works absolutely fine, However, now when if I try and access anything with taxonomy/term/x,y rather than doing a Logical AND, views does a Logical OR operation. Can someone please provide a way of how this can be fixed in views 2. Maybe through some argument handling or something? Here is my export of the view.
