It's saying that they didn't run a grammar checker on it and that the only reason there was no RCF is that they killed the easy submit process.
"Any carry out of the 32-bit addition is discarded. The 64-bit intermediate result will have bits 0 to 31 of the results forced to zeros, i.e., zeros are prepended to the result of the 32- bit intermediate addition." -- Shmuel (Seymour J.)

The 64-bit intermediate result will have bits 0 to 31 of the results are forced to zeros prepended to the result of the 32- bit intermediate addition." I can make a guess that it is saying that the value in the X2 register is treated as an unsigned 32-bit value, which is then added to the signed D2 value to produce a 32-bit (signed?) intermediate value. The 32-bit signed intermediate value is made 64-bits by ignoring bits 0-31 in the result. (That's the "any carry out" part.) That 64-bit intermediate result is then truncated to a 32-bit unsigned result by forcing bits 0-31 to zeros.
