JAR–FCL 1.325 FI(A) – Restricted
privileges
(a) Restricted period. Until the holder of a
FI(A) rating has completed at least 100 hours
flight instruction and, in addition, has supervised
at least 25 student solo flights, the privileges of
the rating are restricted. The restrictions will be
removed from the rating when the above
requirements have been met and on the
recommendation of the supervising FI(A).
Hard to see how this can be interpretted the way you describe. I'd be curious to know if you succeed.
