One of the biggest plot holes/oversights I've seen in a movie

Someone once suggested that they'd mostly die naturally around the same time. Sorta makes sense, barring a few accidents or crimes. I don't think the likelihood of all but one version of a person dying across the multiverse is that high, especially if the last few get stronger.

Technically, it's not simply being "The One" thast grants power. Statham's character says it's because the life force from an alternate who gets killed gets transfered to survivors. So disease and old age would deplete the energy, making it barely anything by the time they die.

You are missing the fact that Yu Law is deliberatly traveling between parallel universes to take out one Yu Law after another to gain there energy.
This hasnt been done before. According to laws of nature there isnt a problem as it has been going on like this for centuries.
But now men created the means to travel between these parallel universes and one guy found out if he kills himself in one of these universes, he gains that guys energy and so sets out to kill himself in all of them using that technology, in other words using means that wasnt intended by nature, bending the rules, creating chaos in order.

It is a very solid story. The movie it self on the other hand is less then mediocre, crappy acting, crappy directing, but as a whole quite enjoyable, storywise. There is simply so much to tell bout stories like these, even though the idea behind it is great, 1 hour and a half isnt enough to explain everything especially when you use it in an action movie where the action is more important then the story. Its sad i agree, could have been done better, but it would come at the cost of less action.
Afterall its Jet Li, you want to see him kick ass and chew bublegum wich was the whole point of the movie to begin with.
Noone is gonna wanna watch a movie like this where they go all technical and explain every single thing. But then you get forum posts like these that go about plot holes and stuff.
So take your pick, what you like, technical boring blabla where everything gets explained from A to Z, or Jet Li kicking people left and right into the wall. If you want both, wich, i would LOVE too, get ready for a 3-4 hour movie because it is simply impossible to get both in that short timespan.

The simplest explanation would seem to be that normally when a person dies in the multiverse, whatever "life force" exists in this story heads elsewhere (heaven, dissipates back to the multiverse, etc). However, the presence of a duplicate somehow disrupts the process and channels that energy into all of the duplicates across the multiverse.

That's not the way it works. Obviously the last "you" alive in an alternate universe will be the only one. That doesn't give them super strength. The death has to be as a result of multi-verse travel for all of the alternates to get more power.

I'm pretty sure the idea is that unless someone upsets causality(as Yulaw does in this movie) every version of you across the mutliverse are "destined" to die at the same time.
