Perhaps short bar, and/or maybe
just trys to pull to that s(l)ide by weight hanging off that side w/o support compared to rest of stump.
Fresh kill easier to see compression and tension patches type signatures in hinge for weight bearing axis/clues.
Much extra cutting if just for Dutching(instead of ramping just in strike pad of facing), and then used too often on what should be last resort type strategy IMHO.
If CoG balanced to fall (or even over to that side a bit), making Tapered Hinge(and thus so also same for going for Dutch Swing) less effective; as not so much fighting to an opposing side lean where Tapered Hinge really allowed to shine.
Reduced length of hinge across reducing leverage to Tapered for pulls even into Dutching, especially if trying for swinger after face close on opposing side as push, no strong tapered pull in unison.
Then, perhaps this offset favored over tapered locally by sawyer.
.
Slide to side/roll some is less of a direct hit too, after thread that needle forward.
.
If just one might think was still on stump after fall, and rolled off to side, but this seems a falling, not bucking style.
>>seems used enough not to be just specialty, but generic solution for them.
Or practicing new cut over and over..
