I know it is possible to lead them that way, so they are basically the same thing as a high boleo, more or less involuntary if the leg is relaxed. But I don't actually dance with anyone at all who does lead them so that it's really like that. It just doesn't happen in reality. People who can actually do that, aren't social dancers who are going to dance with me, or if they are, they're not going to do that in social dancing.
When I later visited BsAs for the first time, I found they just do not do these moves ("forced" or otherwise) in social dancing. You can watch all night at e.g. Lo De Celia and not see even one gancho. Except perhaps from a foreigner who's learned it in a workshop abroad. Locally such moves are considered only for stage tango. A girl doesn't at all mind that kind of treatment if she is a professional being paid to receive it.
