If you're talking about spirit breaker, a while ago it was changed so the swing back doesn't count, it's only when you actually attack. So now, all you can do is "hold" a streak of not bashing.
I think phantom assassin still can do it with her ult (attack, see if the swing back is the crit animation, if not cancel it), but that may have changed (I haven't played in a few years)
I wasn't talking about waiting to see the proc first, but if you have a passive bash and "prime" it by hitting a creep and it doesn't proc, then the subsequent attack would apparently have a higher chance of hitting due to this mechanic, and not the actual % given. You could prime a crit or a bash before fighting a hero, first hit bash can make a big difference. But as stated by someone else this in practice is not easy to incorporate into a game and you are probably just as often wasting time.
Yes, technically, but this is very hard to pull off in a real game.
This is preferable to bara getting 5 bashes in a row and killing you due to real rng. Or playing bara and getting what feels like 0 bashes, again due to real rng.
