Problem 4 (*rtp7*) - CO2 Injection into a 2-D Layered Brine Formation. What is the purpose of additional items in FOFT keyword?

Looking at "Problem 4  (*rtp7*) -  CO2 Injection into a 2-D Layered Brine Formation" for the ECO2N module:

The provided input file (INFILE) has the following  FOFT section:

FOFT ----1----*----2----*----3----*----4----*----5----*----6----*----7----*----8
A15 1          sand  .1000E+01 .2000E+01           .5000E+00 .2200E+02-.5000E+00
A1A 1          sand  .3000E+01 .6000E+01           .5000E+00 .5050E+02-.5000E+00
A1G 1          sand  .3000E+01 .6000E+01           .5000E+00 .8350E+02-.5000E+00
A1U 1          sand  .3000E+01 .6000E+01           .5000E+00 .1555E+03-.5000E+00
A1A13          sand  .3000E+03 .6000E+03           .3000E+03 .5050E+02-.5000E+00

However, in the manual only the first item in each record seems to be documented.

From Tough2-MP users guide, I find on page 48:

Introduces a list of elements (grid blocks) for which time
dependent data are to be written out for plotting to a file called
FOFT_P.xxx during the simulation. The file extension xxx is the
identification number of the processor at which the output was
generated.

-------------------------------------
Record 1: Format (A5) (for MOP(14)=0)
-------------------------------------
EOFT(I)
 Element name. Repeat for up to 100 elements, one per
 record.

Record FOFT.2 A blank record closes the FOFT data block.
