Honestly, this other Snow ( "You know nothing Jon Snow! -- couldn't resist ) may not have known about her. There have been so many prodommes with similar stage names.

Every so often I get my hopes up that a prodomme from yesteryear has returned to the scene only to find out it is a new domme with a similar or the same stage name.

Granted, a particularly thoughtful woman would do a web search to see if her stage name is already taken, but search engines suck these days.
