DWP sending report back to IAS

Hi again. A brief synopsis is..had F2F. 10 days later assessor rang me at hoe in the eveing. I received report from DWP and the report was factual and correct, however she had added a footnote to report that had completely contradicted the original report hence it ony showed 8 points for daily living.
I immediately rang DWP who suggested I follow up with a letter, which I did the same day.
Fast track to last weds when a lovely DM rang me at home and said he totally agreed with me that she had contradicted herself and the footnotes and points didnt make sense to the original report. He said he would make a decision that day, which delighted me. He then rang back later and said his senior manager had said the report needed sending back to IAS for a rework.
I guess my questions are:
Has this happened to anyone before
Will IAS just be upset they are being questioned and not change the points
Will I be called for another F2F
Is it a good or bad thing that report has gone back to them.
Many thanks again for your help

Thank you Gordon for your reply. I guess it is a waiting game to see what the IAS do.
