We learned something similar to the ideas in the clips you showed but it was more formerly organized
I am certain that you are familar with Su Yu Zhang of Taiwan. When we learned praying mantis in the 1980s, my teacher, Tony Yang, patterned much of his teaching from the way Su Yu Zhang taught him praying mantis.
Before any forms were learned, each student had to learn single moving postures/movements. The first set contained 6 moving postures from various praying mantis forms including 8 step, 7 star, mei hua. Each posture had a part B which the opponent could play so you immediately were doing two person drills. There were two additional sets of 6 movements which also included postures and movement from 6 harmony etc. etc..
In addition to these, you also learned a routine of kicks, both in place and moving, along with holding stance training [praying mantis stances].
Also learned to punch and kick padded boards.
Then came the first form--7 hand from the 8 step praying mantis system and this included the B side which made it a two person drill.
During the summers, we would perform these drills and exercises going up and down a 75 foot yard.
Had limited appreciation of what we were doing but looking back, it was a treasure chest of great material.
The training was similar to the following:
