Right, fully acceptable..! IF - for didactic reasons - you want to form a somewhat rigid routine I suggest that you pretty strictly when playing folk tunes in a two-beat, say 8/8 or 6/4, mostly phrased
//// //// or /// /// in a bar, you play pull//// push////, and pull///push/// respectively. I guess that is what you meant earlier. It is very hard to actually see the bellows reversals in your YT clip.
I made one myself a couple of years ago but it isnt't so easy noticing the reversals there either. It's a baritone so the bellows moves very little. I intended to do the same using a tenor or treble to make reversals more visible but I forgot to. Here it is anyway:

Another matter of considerable importance for what "lift" you may get is whether you do the rhythmical beats on push or on pull. Many (I do believe most) players put the beats on push. I did so myself spontanously in the beginning until I found that the pull stroke may give better attack and volume. This also comes more equal to the natural way of bowing with the violin - if we return to that analogy.
