Has anyone noticed that Ritsuka sounds like Yuzuki Yukari in her cover, "Meltdown/Roshin Yuukai"?

Compare the pair: 

Yuzuki Yukari: youtube.com/watch?v=8KgOPPxVdSM

Ritsuka: youtube.com/watch?v=Jj57VDJ9m1E or utaite.wikia.com/wiki/Ritsuka (the demo song).

I recommend listening till the end, before putting forward an evaluation.
