Ditang Quan 地躺拳, also known as Ground Tumbling Boxing,is thought to be about 800-900 years old. Many historians trace its origins to Shandong Province during the Song Dynasty.
The performing of routines with a focus on artistic style, acrobatics, and aesthetic over combat applicability has been around for a long time. The Xiandai (contemporary wushu) 现代武术 has elements of Huatao wuyi花套 武藝(S艺) of the Ming Dynasty mixed with some modern gymnastics and dance 舞术(also pronounced wushu). (Another word, wushu鼯鼠 means flying squirrel. I'm sure there is a joke in there somewhere.)
I know what you mean. The problem with traditional competitions is that there is often no difference in choreography between the traditional and the modern. The difference must be in the criteria for judging them. For instance, traditional taiji competitions see people doing "modern routines" but are supposedly judged on traditional criteria. This routine has a slight "modern flavour" but the choreography is traditional, unlike taiji routines with 720 spins into the splits.
I'm familiar with the system, I just think this looks like a contemporary version of it, like when wushu athletes perform contemporary versions of mantis and long fist.
