Look for PRE (partial redundancy elimination) of stores or partial dead store elimination.  Maybe start with https://dl.acm.org/doi/10.1145/277650.277659 .  See also D29865 <https://reviews.llvm.org/D29865> .

This isn't fundamentally surprising; you have the same number of stores before and after sinking.
