    Write a function that analyzes pairs of encoded transaction flags in a bank's security log to identify legitimate transaction patterns, where each flag is an integer representing combined transaction attributes, and a pair is considered normal if their XOR operation results in an even number. The function should return the total count of normal transaction pairs found in the log.
