This seems extremely unlikely. During its descent, the aircraft was (presumably under AP control) traveling east-west and aligned with runway 26L, which is the most southbound runway at CDG. Therefore, the left deviation from this initial trajectory, either AP- or human-commanded, puts the aircraft even more south of CDG, where there isn't any runway.
Would the crew had erroneously selected e.g. 26R instead of the desired 26L, your explanation could make sense (pilot trying to chase 26L manually at the very last moment), but then we would have seen an initial descent towards 26R, wouldn't we?
Care to explain your point in a more detailed fashion please?
