小白兔，pjiang,射線等有經驗大俠給判斷一下

律師說：

Even though a request for a post-sixth year H-1B extension has been granted, if the I-485 is denied, the H-1B is invalidated. That’s why USCIS says there is no need to resort to H-1B extensions once an adjustment application is filed and an employment authorization document is issued.

以上說法正確嗎？如果NO，如何反駁？
