High Low value in System.Statistics.get_global_statistics

I think the formula is bit shifted, not a power of 32, given the following result:

statistics[] =
        (Common.Statistic){
           type = "STATISTIC_CLIENT_SIDE_BYTES_IN"
           value =
              (Common.ULong64){
                 high = 97
                 low = 841866601
              }
           time_stamp = 0
        },
        (Common.Statistic){
           type = "STATISTIC_CLIENT_SIDE_BYTES_OUT"
           value =
              (Common.ULong64){
                 high = 390
                 low = 2041437072
              }
           time_stamp = 0
        },

The formula for the result would be

value = high << 32 + low

Giving value = (97 << 32) + 841,866,601 = 417,453,694,313

The alternative would yield (97^32) + 841866601 = 3773075507922571775273744352333525624409237957166570158701128042
