I don't remember him relying on the extra "limbs" for movement though. As Iron Spidey, he only had 3 extra arms and they were used for utility purposes, such as seeing around corners. Granted, this is only one image but it seems to me that Octospidey is using those extra limbs in a very Doctor Octopus sort of way.
Okay, but for the people of the MU, how does this strike them as being DOC-OCK-Y (Yeah, without the hyphens it was a sexual.)? Unless someone other than Peter fought and noted those factors... how can they jump to saying "Hey... that's Doc Ock playing Spidey!"? If the dialog hasn't given folks a clue... what the hell could? I read the first few issues and it screamed to me that all those people around Peter are dipshits for not noticing that he's talking and acting like a Raimi movie character. (yes that was a slam against those scenes in Spidey 3 by me.) Peter goes from being a nice guy to a douchebag... not one of them seems to blink. Spidey gets vicious and such and no one takes a hint? But add some robot limbs and it's gotta be called now? That's weak IMO.
Seriously, might as well have him punch Aunt May too.
Slott, you use that, you owe me. We'll talk.
