I'm amazed and saddened that people tend to obsess about things that are actually quite weird. Both the "death hug" and "death grip" shown in the videos are highly unnatural positions for anyone to hold a phone... moreover, different phones have "optimum" methods for getting the attenuation to happen. So, whether its losing "only one bar" or many, isn't even logical to hold up, as each vendor may choose to display bars differently.
I'm listening to the way the guy in the video is speaking, and I can tell he seems to think this is a very important issue. What this is, unfortunately, is an excuse that may cause someone not to purchase the best phone they've ever owned... because they think this will affect them. I even feel that Consumer Reports, in an attempt to sound objective (given its history of glowing reports on Apple) felt the need to push in the opposite direction simply to help its "street cred" with what was likely an extremely vocal group of non-Apple customers.
Kind of sad. I'm still convinced many of the early complaints were more about issues with the proximity bug making calls hang-up by errant touches to your face. All fixed now though...
