this value is computed from selected_tab_index here

https://code.google.com/p/chromium/codesearch#chromium/src/chrome/browser/ses...

and this call 

https://code.google.com/p/chromium/codesearch#chromium/src/chrome/browser/ses...

is always true (means false here)

Maybe using selected (flipped value) is more readable?

I think selected would be clearer here as well as in the callsite
(is_not_selected_tab -> is_selected_tab).
