This is a very interesting topic.
I tend to agree with Andrew Green, but let me add another perspective from my style Yang Style Tai Chi
Yang Chienhou and his brother Yang Panhou learned Tai Chi from their father Yang Luchan.
Yang Luchan learned Chen style Tai Chi from the Chen family and changed it to Yang style.
Yang Chienhou oldest son Yang Shaohao learned Tai Chi mainly from his uncle Yang Yang Panhou and taught the family style intact. Yang Chienhou youngest son Yang Changfu learned Tai Chi from his father Yang Cheinhou. However Yang Changfu changed the family style to basically what we call traditional Yang style today. If you want to see the pre-Yang Changfu style that was practiced by Yang Panhao, first it is rare, but this is the style that Yang Jwing Ming does at YMAA.
Yang Chengfu had a student Tung Ying Chieh who for his entire life taught Yang style Tai Chi. It was not until his son or possibly grandson that Tung style was talked about. And many of Sifu Tung’s students still say they teach Yang style. Also there is Cheng Manching who changed Yang style and as far as I know it was referred to as Yang style or Cheng Manching Yang style.
It was not until Yang Chengfu’s youngest son Yang Zhenduo that the Yang family itself drew a line between Tung, Cheng Manching and the Yang family. It is also possible at that time that the Yang family may have drawn a line between the Yang style of Yang Chengfu and his uncle Yang Panhou.
In the case of the Yang family, new styles of tai chi were made by decree of the Yang family itself.
