Does which 'leg' matter?

I'm thinking of getting new scout this season since my corner takers always fail during corner kick. When I check the scout list, I notice 1 MC with corner specialist but on detail info, he preferably to play with left leg. Did this MC will take corner from both side effectively or only effective from left corner? I wonder if better to get corner specialist with both leg or it doesn't matter which leg for corner specialist. Thanks for reading my curious question and sorry for horrible grammar and English

Its much better to recruit a corner and free kick specialist player who is EITHER FOOTED...

These either footed players tend to play well most of the time than other players...:)...
