Bug report: git checkout introduces local changes

Background: (from memory)
Branch A had a file X added to it
Branch B had a copy of the file X added to it (in a different location)
Later, Branch B was merged to branch A

Steps:
1. git checkout A
  No local changes
2. git checkout B
  File X is deleted

What did you expect to happen? (Expected behavior) Checking out a branch should not introduce local changes

What happened instead? (Actual behavior) Checking out branch B introduced a local change, deleting File X

Additional information: Switching back from branch B to branch A results in no local changes
