Problem comparing 2 docx files

[bs_dellacqua]

I'm using docx4j 3.3.6 and I'm trying to compare the two attached docx file Issue_#34953_10123855.docx and Issue_#34953_10123853.docx with the code contained into CompareDocumentsTest.java;
the only difference between the 2 files is the text "FIN DE LA CLAUSE" inserted at the end of Issue_#34953_10123855.docx but the docx with the differences (OUT_CompareDocuments.docx) reports also that the same text has been before removed and then inserted.
Do you have any idea about this strange behavior ?
