@gouri From my experience yes.
@netmeg High authority sites with lot of backlinks are immune to this.
Another beautiful outcome of this update is that the some sites will rank when the keyword is repeated around 5 to 15 times in an 300 - 350 words article. But if you try to do the same your page wont rank at all.
