git renommer/supprimer la confusion

Je avoir une confusion au sujet d'un particulier git comportement:

Voici les étapes et de la situation (la liste des commandes sont également donné plus tard):

1. J'ai deux branches: le maître et XBranch
2. Il y a un fichier src/a.txt dans deux d'entre eux. C'est le contenu qui est "Contenu"
3. Dans XBranch-je renommer src/a.txt pour src/b.txt à l'aide de: mv, git rm, git add.

4. En maître renommer le fichier a.txt. Au cours de commettre je n'ai git rm src/a.txt mais oublié de le faire git add src/b.txt
   En master, je n': git rm src/a.txt et git commit

5. En master, j'ai modifier le contenu du fichier b.txt "New Content

6. En maître, je ne git add src/b.txt et git commit
7. En maître, je n': git merge XBranch

Le fichier src/b.txt les conflits, ce qui est parfaitement compréhensible.
Mais le contenu est "Old Content". Pourquoi?

Pourquoi pas est quelque chose comme:

<<<<<<< HEAD
New Content
=======
Old content
>>>>>>> XBranch
