I have heard this view, but is it actually supported by the data? That is, do comebacks happen with any significant frequency in high-level DotA?
For example, in all of the finals of the recent International, there was a leader at 10m who won the game. I'm not going to go through all the games and check, but I'd guess we'd find this to be true the vast majority of the time in professional DotA games, as it is in League games.
Not to make too sweeping of a generalization, but I expect it is inherent in games with an economy and relatively low random factors. On top of the normal expectation that who gains a lead is likely to be more skilled, economies that allow you to build additional strength via the dominance conferred by your current strength reinforce existing leads.
AFAIK the "deathball" strategy recently became really dominant leading up to The International. The most recent balance patch after The International included a lot of measures to swing it back the other direction.
The most recent patch introduced a comeback mechanic that was so powerful that it resulted in comebacks becoming the norm. It got toned down within 2 weeks.
