Not necessarily.
A good corner can read a receivers eyes and wait until the right moment to jam an arm or two up in there and do so with extreme prejudice. If you can hold your water and avoid egregious contact until the moment the ball arrives and then attack the area between the receiver's hands, you're not going to get flagged even if you have your back to the ball. Officials are pretty good about not calling a guy for sound technique.
The only instance where getting your head around can provide some benefit (in regards to officiating) is if you do get your head around and make it look like you're playing the ball, some officials might you give you a little extra leeway with contact. If you quickly and discreetly slap a guys forearm (without actually hooking or grabbing it) while you're turning around you can make it look like some incidental hand-fighting and you might get away with it. Typically you'll get flagged, but if you don't have your arms extended when you do it and it's 3rd/long, stripes generally does not want to make a call that decides possession.
In the example of Wallace getting called against Claypool, he wasn't really in position to try that though. He was beat on the route (which I don't give him too much grief for because his job was to be playing the sticks as much as the receiver in that down/distance) and was already guilty of holding Claypool's right arm just to keep him close. He's just not a good enough natural athlete to recover from that position and had no chance to hide the grabbing of the other arm by incorporating it into a turn. His only shot was to stay oriented on the receiver, watch his eyes and then attack the middle of his catch radius like a junkyard dawg when Claypool's eyes got big.
