Correct setting of url-manager yii1?

Question

Yii

There is a rule like

'<controller:\w+>/<action:\w+>/<id:\w+>/maincategory/<maincategory:\w+>'=>'<controller>/<action>',

When following a link like

http://parsercsv.loc/model/model/fusion_24/maincategory/vyhlopnaya-sistema_55

Controller Model actionModel method Printing
the $_GET array prints

Array ( [fusion_24] => maincategory [vyhlopnaya-sistema_55] => )
Должно быть 
Array ( [id] =>fusion_24 [maincategory] =>vyhlopnaya-sistema_55)

Has anyone encountered such a thing? And how is it decided?
