Why is the IFS needed here?

This looks wrong. The value assigned to LIST is never actually used,
and here is a part of the output of bash -x:
++ set
++ grep '^[a-zA-Z][a-zA-Z0-9_]*_HERE'
++ sed -e 's|=.*||;'
+ LIST=
+ for PVAR in '$*'
++ echo HERE
++ sed -e 's|_HERE$||g;'
+ VVAR=HERE
+ '[' -n STORED ']'
+ eval SVAR=HERE_STORED
++ SVAR=HERE_STORED
+ eval 'HERE_STORED=$'
++ HERE_STORED='$'
+ eval 'HERE=$HERE'
++ HERE=
+ eval 'unset HERE'
++ unset HERE
+ for PVAR in '$*'
++ echo STORED
++ sed -e 's|_HERE$||g;'
+ VVAR=STORED
+ '[' -n STORED ']'
+ eval SVAR=STORED_STORED
++ SVAR=STORED_STORED
+ eval 'STORED_STORED=$'
++ STORED_STORED='$'
+ eval 'STORED=$STORED'
++ STORED=
+ eval 'unset STORED'
++ unset STORED
+ IFS='
the variable names HERE_STORED and STORED_STORED look wrong.
