You set the parameters to be ignored, but in case Google doesn't or glitches or something on those same pages you've said to ignore due to the parameters you put a noindex and rel=canonical to the page without parameters.
The noindex is a backup in case the WMT setting doesn't work. It's not a "proper page" you want indexed. You want the pages without the parameters indexed not the pages you've said to ignore the parameters on.
Here maybe I'm missing something:
^^^ This is the one you want indexed. See no parameters.
^^^ This one gets a noindex and rel=canonical pointing to the page without parameters.
Please, someone explain to me how that could possibly keep the page without parameters out of the index?
