Is Nintendo and Bethesda's cooperation recently over their single player focus?

With that recent Bethesda video about single player games at the Game Awards, I wonder if that might have played into them doing more game work on Nintendo? 

 

After all, what is Zelda and Mario but a single player game, and they dominate on the Switch where the other consoles are dominated by multi player games?

Mario oddessy  is actually 2players! I played the whole  game  in co op with my son.
