Pretty sure the rule goes by that "only a stand can attack/harm another stand". However since stands are psychic manifestation of someone's spirit, essentially the user and the stand are two individuals but also the same entity, just different aspect of it. As such, the stand's arm is the user's arm, similar to how most of stands and the user share injuries and senses with each other, besides the automatic stands and a few odd balls with special features.

As demonstrated by Jotaro stepping onto the sand with an extreme force to keep Iggy in flight using his/Star Platium's leg during the fight with N'doul. Or how Dio punched with his/The World's arms during the road roller scene. Another example would be when Avdol tried to seemingly touch Holly's stand infection with his bare hands thinking that she fainted after suddenly developed a stand.

As long as the stand isn't already called out and separated from the user's body, the user and the stand are essentially one and thus it is possible to touch or otherwise interect with other stands physically without having their stands clearly visible at the time.
