Qualified

I am thinking of applying for eea2, as my cousin brother is an EE citizen. He has been living here for more than four years. First two and half years he worked in east London based company. Later he had a sudden heart attack, which resulted his losing the job. His doctor prescribed him not to take another job, as he is not fit yet. Last year he had to claim for employment and support allowance. It has been now one and half year he is not working, and taking employment and support allowance.

He is settled here. He has got eea1 registration card. But If I want to apply as his extended family member. I have to prove he is a qualified worker according to article 6 (1) . he is not working currently due to sickness. Could you please tell me, would he be considered as a qualified worker or not. I found in Eea regulations 6 ( 2 )(a), A person who is no longer working shall not cease to be treated as a worker for the purpose of paragraph (1)(b) if
(a ) he is temporarily unable to work as the result of an illness or accident;

Please advise .
Thank You
