That has been a standard bucking cut, more or less, for a long time here in the PNW.
If there is top bind you do the vertical offside cut first reaching over the top of the log, draw over the top on the belly of the bar, continue on down the near side with the tip, then slide on underneath and release by cutting upwards through the "square" with the top of the bar. The bar never leaves the wood from start to finish when a smooth sawyer wields the saw well.
With bottom bind, after the first offside cut, you pull the saw free, place the bar under the log and cut upwards, then draw the bar back and again with the tip cut upwards on the near side, then push over the top and complete the cut down through the "square". In this case the last three cuts are performed all in a continuous motion, three sides done without removing the bar from the log.
In both cases, all the kerfs are in alignment, and the depth of the cuts are generally equal, though that may well vary depending on degree of bind.
