If op1 is ERROR the behavior is to not perform any assignment and return NULL. However, if the RHS was a by-value returning function, we'd instead emit a notice and return the RHS as the return value (even though the value was not assigned to anything -- the temporary is immediately destroyed). This normalized the behavior to always check for an ERROR in op1 first.
