read splits the line by $IFS as many times as you pass variables to it:

while read var1 var2 ; do
    echo "var1: ${var1} var2: ${var2}"
done

You see, if you pass var1 and var2 both columns go to separate variables. But note that if the line would contain more columns var2 would contain the whole remaining line, not just column2.
