The interpretation of this report aligns with what was mentioned regarding the first narration: if someone believes that ghusl does not suffice and wudu is required afterward, this constitutes an innovation. It is also possible that this narration specifically excludes the ghusl of janabah because it is recommended for other types of ghusl to perform wudu beforehand. If wudu is delayed until after such a ghusl, it would be considered an innovation.
