Why does StandardNames output different amounts of data?

edit

So, when I change between StandardNames: 0 and 1 I get different amounts of data.

$results = $session->Search("property", "RE_1", "(L_ListingID=0+)",
    [
        'Format' => 'COMPACT-DECODED',
        'StandardNames' => 0,
        'Limit' => 1,
        'Select' => '*'
    ]);

Why does one output only show 50 or so elements of data while the other shows 600? I thought StandardNames only change the names from system to standard so it's more readable? Why does it retract some data based on 0 and 1?

StandardNames: 1 (50 or so elements of data)
