Странный результат выдает операция pack/unpack в Query

static void testQueryPack(Args _args)
{
    Query                q1, q2;
    QueryBuildDataSource qbds1, qbds2;
    container            con;
    ;
    q1    = new Query();
    qbds1 = q1.addDataSource(tablenum(InventTrans));
    qbds1.addRange(fieldnum(InventTrans, StatusIssue)).value(queryValue(StatusIssue::Sold));
    qbds1.addRange(fieldnum(InventTrans, StatusReceipt)).value(queryValue(StatusReceipt::Purchased));
    qbds1.addRange(fieldnum(InventTrans, StatusReceipt)).value(queryValue(StatusReceipt::None));
    qbds1.addRange(fieldnum(InventTrans, StatusIssue)).value(queryValue(StatusIssue::None));
    info(qbds1.toString());
    con = q1.pack();
    q2  = new Query(con);
    qbds2 = q2.dataSourceTable(tablenum(InventTrans));
    info(qbds2.toString());
}

чем это можно объяснить?
