I'm not sure how this "confirms" anything, especially as easy as it is to fool SiSoftware.
Intel's upcoming i7-9700K CPU has been found on the SiSoftware database, confirming several previously specifications of the processor. For starters, the processor is listed as using a Coffee Lake S client platform, which suggests that the processor will be usable on today's 300-series motherboards after a BIOS update.
