def build_qwen_chat_input(
    tokenizer: PreTrainedTokenizer,
    messages: List[ChatMessage],
    context_len: int = 8192,
    max_new_tokens: int = 256,
    functions: List[dict] = None,
) -> List[int]:
    """ https://huggingface.co/Qwen/Qwen-7B-Chat/blob/main/qwen_generation_utils.py """
    query, history = process_qwen_messages(messages, functions)
    for q, r in history:
        messages.extend([ChatMessage(role=Role.USER, content=q), ChatMessage(role=Role.ASSISTANT, content=r)])
    messages.append(ChatMessage(role=Role.USER, content=query))

    for i, x in enumerate(messages):
        print('messages', i, x.role, x.content)
    max_input_tokens = context_len - max_new_tokens
    system, rounds = parse_messages(messages)
    system = "You are a helpful assistant." + system  # fix system prompt

为什么已经输入messages以后，还要执行

messages.append(ChatMessage(role=Role.USER, content=query))

此时messages已经包含用户输入的问题了，但query也是用户输入的问题，这样的话不会导致llm的输入变成下面这样吗？
system
user_input
user_input
