I wouldn't conclude that from an Intel Employee even if they did claim it because they(Intel) already lied multiple times in this afair.
But they didn't even do that, they just said desktop processors are affected, this doesn't say mobile ones are not.
Many companies have already reported that their telemetry records many crashes with the exact same symptoms and software on their laptops while AMD still isn't affected.

Mind, that this is just the company which published the initial reports that the defects in desktop CPUs are systematic, so I can see why Toms Hardware deems their Post a reliable source.
