LGTM. A couple of potential changes, but I leave that to you if you think it's better:
1. A shorter statement:
Splat refers to a vector of identical scalar elements.
2. We could add a sentence for the historical background:
The term is based on the PowerPC Altivec instructions that provided this functionality in hardware. For example, "vsplth" and the corresponding software intrinsic "vec_splat()".
