Module rustc_mir_transform::ssa

We denote as “SSA” the set of locals that verify the following properties: 1/ They are only assigned-to once, either as a function parameter, or in an assign statement; 2/ This single assignment dominates all uses;

As a consequence of rule 2, we consider that borrowed locals are not SSA, even if they are Freeze, as we do not track that the assignment dominates all uses of the borrow.
