Hi Hussey,
In the current NFD implementation and also the previous versions, the
PIT performs Interest aggregation if the same Interest is requested
again. So there will be only one PIT entry if the daemon gets requests
from two different downstream routers for the same prefix.
Regarding your example, the PIT of C would look like the case on the
right hand side: "same entry with corresponding data".
If you are interested in the implementation details, more information
can be found in the NFD Developer’s Guide (Link:
http://named-data.net/wp-content/uploads/2014/07/NFD-developer-guide.pdf).
