Rule of thumb, the closer the tie off from the last exit, the better.
In this case its pretty far from the last main. 2 knots on the same string doesn't make much sense and the second to the last main is right there and big enough for cross tie off. Did she give an reason why she did it this way? This looks pretty bad IMO.
