For a clean design you would need not just two DictReader instances, but one
DictReader for every two lines. 
However, with the current DictReader implementation, the following works,
too:

import csv
import sys

reader = csv.DictReader(sys.stdin)

for record in reader:
    print record
    reader.fieldnames = None
