Changing designation of assessing officer

I just filed online ereturn in my office for two staffs and the designation of assessing officer is taken from the pan card of accesse.
So until your pan card no changes your assessing officer wont change. Even though you file return from any place in india, you work any place in india, your assessing officer will be the same from where you got your pan card issued. EVen I am not sure about this but this is what this website portrays as:

enter your pan card and it shows your assessing officer...
