The article is referring to GPU compute kernel (https://en.wikipedia.org/wiki/Compute_kernel), not the term kernel used in ML/NN/etc.

…aren't they the same thing

		They're not, but I also misunderstood the original question, they're referring to the correct definition of kernel. I thought they were confusing the GPU kernel with https://en.wikipedia.org/wiki/Kernel_method or https://en.wikipedia.org/wiki/Kernel_(image_processing)
