NEC-LIST: NEC 4.1 corrections question

I'm trying to figure which corrections to NEC 4.1 published in the
ACES Newsletter have been made to the version I have. I ran into a
anomaly concerning a correction from 3/96. In RDPAT my copy has the
lines:

            CALL FFLD (THA,PHA,ETH,EPH)
            ETH=ETH*CEXP(-(0.,1.)*XKU*RFLD)/RFLD
            EPH=EPH*CEXP(-(0.,1.)*XKU*RFLD)/RFLD
            ERDM=0.
            ERDA=0.

the correction says that it should be:

            CALL FFLD (THA,PHA,ETH,EPH)
            RDIST=SQRT(RFLD*RFLD+THET*THET)
            ETH=ETH*CEXP(-(0.,1.)*XKU*RDIST)/RDIST
            EPH=EPH*CEXP(-(0.,1.)*XKU*RDIST)/RDIST
            ERDM=0.
            ERDA=0.

The anomaly is that the discussion indicates that lines 2-4 above are
new, not replacements to lines 2-3 in my copy. Could someone explain
this anomaly?
