It's because they just use the name of the actual AVX ops (https://software.intel.com/sites/landingpage/IntrinsicsGuide/ https://software.intel.com/sites/landingpage/IntrinsicsGuide...). This is a low-level lib. They don't want to hide anything. If you see _mm* you know you are using AVX and which version (which is important to know which CPU is supported). High level lib do use more natural names.

The commenter was pointing out that intrinsic functions shouldn't just be called functions (I have no strong opinion on that comment). He wasn't commenting about the names of the functions themselves.

  Ah ok, I didn't understand.
