That's not unreasonable, but the author's justification for this is a cautiounary tale of self-censoring one's own arguments or descending into fallacies in the process. Neither of these are specifically or inherently the product of steelmanning. Poor arguments can occur while using any discussion technique, and I don't see anything special about the principle of charity that requires people to be warned off of it in any way. "Don't make poor arguments while trying to understand the counter claim" seems perfectly sufficient without going to these lengths & recommend skepticism of steelmanning in general.
