Isn’t the actual quote “Tuition benefits external to Georgetown will be used to reduce or eliminate first your family financial responsibility, if applicable, then your student loans or federal work study before any adjustment is made to your Georgetown scholarship.”(https://finaid.georgetown.edu/financial-resources/outside-benefits)?
Tuition benefits for employees of other universities (assuming that is what it is referring to) are not the same as outside scholarships, although I agree this could easily be misunderstood since the entire page is linked as “Outside Benefits” and no specific statement appears to be made about how outside scholarships are treated even though you are encouraged to search for them.
It also might be regarded as somewhat questionable to treat educational insiders more favorably than the general public in this regard, if that is indeed the case, although the quote from the bulletin above contradicts this statement about tuition benefits and suggests that no distinction is made.
