In practice, it doesn’t seem to work that way. Lafayette treats Men’s Fencing and Women’s Fencing as separate teams, and the men and women appear to compete separately in post-season fencing events, such as the NCAA Mid-Atlantic/South Regional. In the 2015 Regional, for example, a Lafayette fencer placed 21st in Women’s Epee:

In other words, there doesn’t seem to be any obvious difference between the Lafayette Men’s/Women’s Fencing Teams and anyone else’s Men’s/Women’s Fencing Teams, even though NCAA officially classifies Lafayette’s program as “Mixed”.
