If you look up the previous awards, one way they list them is by university, as a record of funding achieved in total.

So some universities show having received X million for the nsf GRFP, whereas others, who might have only had one student receive the GRFP, might list it once, as $44k if they received it that year, or if the year before, 44kx2 = $88K, etc. PIs seem to never be the student themselves - I looked up some others, and they're dean provosts, etc. Perhaps it's meant to give credit to the students' mentors/university for having helped them get this far.
