It does mean lots of sections, yes. You can bind the section to the same field as your control, if you like, to keep your data source a little cleaner. I don't understand the second question: "and how the final form follow the second view's result?" You may need to have a checkbox or something for the user to indicate when they are finished filling out the form and then, if that that field is true, have the form open in "final" view, if I am interpreting the question correctly. I believe you can have conditional formatting in a browser form -- I just used the design checker on a form with conditional formatting that was set to InfoPath and InfoPath Forms Services for compatibility and didn't get an error.
