You read wrong. Bill worked for numerous brands (as stated above), and made a trainerkite for SS years ago. He was with Switch since the beginning (2011 I think) and left last year. The Legacy 2, Element 5, Helium 2 and Nitro 6 were his last designs at Switch. He is now with Slingshot.
Switch now 'buys' models from different manufacturers. The Element V6 is basically an Ikon Peak, the Krypto is an Ikon Blind and the Helium is a Storm Voyager. I can't see much difference between the Peak3 and Element6, but the Krypto has a different bridle, so it has been developed further. Maybe the same for the Helium (although I read it flaps when depowered... gotta love that F-One DNA, lol)
Who knows... maybe the original Krypto design (the 3 strut one) will be released by some other brand at one point. Looking at all the current Krypto video's out there, I can't really say I'm impressed with the kiteloop performance. Seems really sluggish to go back to 12 after the loop... other than that, it seems to do the job just fine.
Ikon is run by 3 people, one of them being the ex Airush designer, Benoit Menetrier.
Switch never stated that the kites are rebranded Ikon's and Storm's btw. But it's very clear if you compare them.
