The way I think about it is that for every tiny little decision/event (I'm talking all the way down to a sub-atomic level here people) their is an infinite amount of universes created for the other infinite amount of actions that could of taken place. That mean's that there are parallel universes for absolutely any and everything that has ever happened or could have happened.

That said I think it is possible for any sort of ASB, but I do note that it maybe isn't the most probable thing to happen given the situation but somewhere there is an alternate universe where it did happen. So I try to make things go differently and hence in most alternate histories we assume that everything else stayed the same unless mentioned, and this is mostly done to make things simpler, as if you think too hard about this sort of stuff you'd never finish your timeline.

For example, as I type out this message, think about how my fingers are moving the air in ways differently to if I wasn't typing. Think how this change in air flows might change the world. It might be the slight change needed to push a bullet on course to kill the Queen of England! Thinking about how your every single action changes the world around you seriously weirds me out and fills me with a glee of thinking just how me typing slightly quicker than usual might change the world. If this is blowing your mind too much, let me simplify this a bit. How will you reading this stuff change the lives of the people reading this? Will I inspire someone to take up a career in physics perhaps?

Basically to sum up, if we think too much about this sort of stuff then we risk just never going anywhere with our time lines, hence we simply things and assume most other things stayed the same. Otherwise the possibilities are endless to what could happen!
