Multiple Conditional Processes on Submit - Confused!

Question

I have a Form Page based on a table where the user can update the data. I want to capture changes in a history table.
Simplified, the tables are:
Table PKey Varchar Columns
UPDATEABLETABLE ID1 TEXT1 TEXT2
HISTORYTABLE ID1 DESCRIPTION
In addition to the automatic row update process I created 2 conditional processes:
Process UpdateText1
Source: INSERT INTO HISTORYTABLE (DESCRIPTION) VALUES ('TEXT1 Changed to ' || :P1_TEXT1);
Process Point : On Submit - After Computations and Validations
Condition: Type: Value of Item in Expression 1 != Expression2
Expression 1: SELECT TEXT1 FROM UPDATEABLETABLE WHERE ID1 = :P1_ID1
Expression 2: : P1_TEXT1
Process UpdateText2
Source: INSERT INTO HISTORYTABLE (DESCRIPTION) VALUES ('TEXT2 Changed to ' || :P1_TEXT2);
Process Point : On Submit - After Computations and Validations
Condition: Type: Value of Item in Expression 1 != Expression2
Expression 1: SELECT TEXT2 FROM UPDATEABLETABLE WHERE ID1 = :P1_ID1
Expression 2: :P1_TEXT2
The issue is that if I only change 1 item (either one), both items return a line to HISTORYTABLE. Only if there are no changes or If both have changed I get the expected result.
I've tried changing the Process Point and sequences, etc. without any improvement.
Any ideas gratefully received!

Hello:
If you just need to track changes to a record without needing to know what field in the record was changed a simply 'MINUS' query will work to insert the changed record into the history table.
insert into history_table
select col1, col2, col3, col4... from tab where pk=:P_pk
minus
select :p_col1,:p_col2,:p_col3... from dual     // p_col1,p_col2.. are page items corresponding to col1,col2...The above code is in a 'After Submit' page process that fires before the 'Automatic Row Processing (DML) ' process
