Yes it does. Also just a tidbit to make this post a little longer, you can instant pivot grab on the spot if you (assume face right) dash left and simultaneously press z + c-stick right. Dunno if this is too useful for Sheik specifically, but hey, increase in grab range.huh, interesting. If dash didn't limit so many options, this would be able to replace shieldgrab + other things in a lot of situations. Cool :D
I think you can also use Cstick to replace A for doing this, correct? This makes it also easier to do pivot shield grab.
