Thank you again, but....
I also understand "nonconsecutive" period.
One CPA told me that the 5 years reset after the first benefit (aka first home sale). Since my 5 years term was reset on the date of the first home sale, the 4 months living at the second home 4 years ago is not part of the 5 years.
I even cannot find that "reset" rule any other place. I asked the CPA to send me a reference of the "reset" rule but am not sure if he will response.
