Lying no, I wouldnÂ’t call it lying just yet, but I currently believe it is fuzzy truth.
there is reason to doubt his claim
And sorry, but you are correct he is claiming relation to the Yang family via his grandfather Yang Xiao Hou who I assume is Yang Shaohou. So if he is the grandson of Yang Shaohou he is the son of whom?
Yang Shaohou (Yang Zhao Xiong) had two sons Yang Zhensheng and Yang Wen Zhong, whom Yang Fukui of the article never mentions. Also Yang Fukui is not listed on the Yang family site or in the Yang family tree. But then this is not exactly proof of his lineage not being from the Yang family, they just recently added the Yang Shaohou line to the page.
The only other possibility for his Grandfather is Yang Zhao Yuan who died young and had one daughter Yang Cong.
The only children listed for Yang Zhen Sheng (the son of Yang Shaohou) are Yang Yu Pin, Yang Wen Zhong (Jin Pin) who died in 1989, and Yang Wen Bin (Pin Er). Which one is Yang Fukui?
He (Yang Fukui) also claims to have done push hands with his grandfather who I am assuming is Yang Shaohou who died in 1930 so to have done push hands with his grandfather Fukui would now have to be almost 80 years old or older. How old is Yang Fukui?
But then he could be talking about his other grandfather which then says he did not train with the Yang family. Also, historically members of Taiji families that are trained by those families do not train other arts. It appears Yang Fukui has trained other arts.
Is this the same Yang Fukui that you are talking about?

Also as far as I know all of Yang Shaohou family is in Hong Kong and Yang Fukui never mentions Hong Kong.
But I am willing to check into this further, maybe his claim is legitimate, but at this point I have my doubts but I will check and get back to you
EDIT:
One more question; Who was Yang Fukui's teacher for Yang stlye? He never actually says who he learned it from.
EDIT: Sorry, one more thing
You have twice now written the name yang funaki, is this the Yang Fukui of the posted article?
