..has supervised at least 25 student solo flights...
In western countries, it is still a generally accepted principle that if a thing is not prohibited, then it is allowed.
...a solo flight executed by a NPPL(SSEA) student...
This is a 'student solo flight' and it doesn't say anywhere that It doesn't count.... So it does!
And any other student flight that the FI was entitled to supervise would count as well.
Let's not try to make this stuff any more complicated that it already is!
