How to print the output in correct order?

Hi,

while using following awk commend I’m getting confused,
The output is not like as the row present in input files, can anyone explain and tell me how to print in the order like in input.

Code:
value=$(awk 'FNR>1 && NR==FNR{a[$2]=$4;next} a[$2]{sum[$2]+=$4} END {for(i in sum){printf i"\t"sum[i]/2"@@";}}' file1.tsv file2.tsv)
echo $value > file.tsv
sed -i 's|@@|\n|g' file.tsv


File1.tsv
Code:
Col1 col2 col3 col4 
1 952 sa 140
2 124 sb 130
3 950 sc 92
4 125 sd 150
5 800 se 110

File2.tsv
Code:
Col1 col2 col3 col4 
1 952 sa 130
2 124 sb 150
3 950 sc 90
4 125 sd 160
5 800 se 100

Result file.tsv
Code:
col1 col2
950 46
952 70
124 65
800 55
125 75

pamdeinterlace(1)					      General Commands Manual						 pamdeinterlace(1)

NAME
pamdeinterlace - remove ever other row from a PAM/PNM image SYNOPSIS
pamdeinterlace [-takeodd] [-takeeven] N [infile] You can use the minimum unique abbreviation of the options. You can use two hyphens instead of one. You can separate an option name from its value with white space instead of an equals sign. DESCRIPTION
pamdeinterlace Removes all the even-numbered or odd-numbered rows from the input PNM or PAM image. Specify which with the -takeeven and -takeodd options. This can be useful if the image is a video capture from an interlaced video source. In that case, each row shows the subject 1/60 second before or after the two rows that surround it. If the subject is moving, this can detract from the quality of the image. Because the resulting image is half the height of the input image, you will then want to use pamstretch or pnmscale to restore it to its normal height: pamdeinterlace myimage.ppm | pamstretch -yscale=2 >newimage.ppm OPTIONS
-takeodd Take the odd-numbered rows from the input and put them in the output. The rows are numbered starting at zero, so the first row in the output is the second row from the input. You cannot specify both -takeeven and -takeodd. -takeeven Take the even-numbered rows from the input and put them in the output. The rows are numbered starting at zero, so the first row in the output is the first row from the input. This is the default. You cannot specify both -takeeven and -takeodd. SEE ALSO
