Watch Match 2 - Falcon(LeeHarris) vs Wolf(Tony).
0:49 - Dashdance, trip
0:58 - Dashdance, no trip (about 5 back and forths)
1:02 - Dashdance, 3 changes in direction, then trip
1:38 - Dashdance, 3 changes in direction, no trip
1:42 - Dashdance, 10+ changes in direction, no trip
1:51 - Dashdance, no trip
Conclusion: Dash dancing is possible - at least with captain falcon - but requires a specific timing, otherwise you trip.
