Unexpected result from awk

Hello,

Giving those commands:

Code:
cat > myfile 
1 
2 
3 
^D 
cat myfile | awk '{ s=s+$1 ; print s}'

The output is:

Code:
1
3
6

It seems like this command iterates each time on a different row so $1 is the first field of each row.. But what caused it to refer to each row ?.
What I mean is, how it knows that for the second iteration for example, $1 should be the first field of the second row rather then the first field of the first row again ?

MSQL_RESULT(3)															    MSQL_RESULT(3)

msql_result - Get result data

SYNOPSIS
string msql_result (resource $result, int $row, [mixed $field]) DESCRIPTION
msql_result(3) returns the contents of one cell from a mSQL result set. When working on large result sets, you should consider using one of the functions that fetch an entire row (specified below). As these functions return the contents of multiple cells in one function call, they are often much quicker than msql_result(3). Recommended high-performance alternatives: msql_fetch_row(3), msql_fetch_array(3), and msql_fetch_object(3). PARAMETERS
o $ result -The result resource that is being evaluated. This result comes from a call to msql_query(3). o $row - The row offset. o $field - Can be the field's offset, or the field's name, or the field's table dot field's name (tablename.fieldname.). If the column name has been aliased ('select foo as bar from ...'), use the alias instead of the column name. Note Specifying a numeric field offset is much quicker than specifying a fieldname or tablename.fieldname. RETURN VALUES
Returns the contents of the cell at the row and offset in the specified mSQL result set. PHP Documentation Group MSQL_RESULT(3)
