为什么只有后两个元素倒序了？ 这是代码：

user1 = {
    'username': 'oliver',
    'first': 'cai',
    'last': 'jizhou',
}

for name in sorted(user1.values(),reverse=True):
    print(f"The {name} is real.")

输出：

S D:\python_work> & D:/Python3.8.5/python.exe d:/python_work/demo92.py
The oliver is real.
The jizhou is real.
The cai is real.
