As they are the same person with different memories, I'll leave you some pages where he does that movement while being Kaneki and Sasaki:

He likes to use his legs and tights... and we love it!

You didn't have to go out of your way to prove me wrong *cries* I was just hoping he'd come back...it was a feeling I had and now I'm sad...because you shattered my hope. But yeah I wasn't really expecting it to be true :/ sadly. Still thanks for actually going through the trouble of answering me, pretty cool of you ^^ It's still a pretty badass move and I love Kaneki!!!

Oh, no, no. That wasn't my intention. Please don't be sad...
Hahaha, I began to write before reading it all. You're welcome >U<
I love him too.
I'm not really sure if they are the same person or not, because now I see it as him losing his memories, but if it is something like multiple personalities (I need to study that to understand it), I... I... I just hope they both will be well... :'(

I think they are the same person, not different personalities. I mean if you take Kaneki's memories away and put him in a new environment as a ghoul investigator he would turn out like Haise, because at the center of Kaneki is a really kind boy who's trying to protect everyone but especially the people he loves. So they are the same person...at least that's what I thought until you said that...now I'm not sure anymore...I mean Haise has been seeing Kaneki in his mind, which I thought it was a manifestation of his memories, trying to come back but now I can't be sure. I just really miss him :( I love Haise, but he's incomplete, he doesn't remember what he went through, he doesn't remember his loved ones...and it's heartbreaking. But some memories are seeping through, so maybe Kaneki isn't that far off from returning...hopefully. Sorry for the huge answer lol

There is no need to apologize. Thank you for your reply :)
I prefer to think he lost his memories. But sometimes I have my doubts, because Kaneki and Sasaki have said "I might dissapear" a few times.
However, I've seen this way of approaching the "lost memory" topic in other manga: "if I get my memories back, it would mean I would lose the ones that I've now". Does it really work like that in RL?
I also hope he can remember. It would be awful if he remembered too late... (after killing/hurting the ones he loves).

Yeah, you're right...they sometimes make it seem like they aren't the same person.
No, I'm pretty sure that's not how it works. But the feeling that Haise has is probably if the memories come back he would no longer exist...because in the end he is Kaneki. Not sure if things are that simple, I'm pretty sure if the memories do come back, now he wouldn't be Kaneki nor Haise but a combination of the two...maybe.
But that's the feeling I get, that maybe he'll only remember after he does something really bad to someone he cares about...but hopefully the mangaka won't make us go through that!!
