I will tell you exactally what happened. I have stated this several times in this forum over and over again. After I won my case before the judge. My lawyr from Allsup(been a disability lawyer for 15 years) flat out told me since I won my case based mainly on mental issues do not do any type of work whatsoever unless you are ready to go back full time. do not work 1 hour or 40 hours. If they see upon a review that you can go out in the public and do any type of work they will take your benefits RIGHT NOW. This was told to me in 2009 and I remember those words just like yesterday. He said it is not right but thats how they take people off the roles. I know it stinks as I want to do some type of work but nothing pays me what my SSDI does. He even told me not to go back to school as they will cancel me this way as well. So I am stuck. I do not think your brother has a case but I would also fight it. I have a feeling they will tell you what I just told you. Keep us posted.
