The application code is issuing a parse call 3 times. Taking the example of the DBMS_SQL package, if you call the PARSE procedure three times for three executes, you'll see three parses accounted for in the SQL Trace file. Some of them might be "soft" parses, but SQL Trace (and TKPROF) still record it as a parse...
