If I were going to write 10 unique articles and submit one to each site, then I would only get 30 backlinks. But if I submit all 10 to each site, then I get 300. If you spread your links around to a lot of different internal pages, this can do wonders....
I'm not sure where you get your numbers or exactly what examples they refer to, but it seems you're suggesting submitting 10 articles per site, with 30 article sites publishing your articles.
Not likely to look natural to Google, nor is it likely that these links will help you with organic rankings.
My emphasis below...
If you use a different title at each directory, at first, you will probably see the same article ranking multiple times, but within a few days, Google's competition filter catches up and usually only one remains. But in those few days, you get more/extra organic traffic.
It's more correctly called a duplication filter, and Google does not like duplicate content. They don't like short term links designed to boost your rankings either. They might even consider the technique to be spammy.
Hard to say in a few days time how much organic traffic you will have picked up. It's not likely to be much, and that's not the kind of traffic you will retain... particularly since those articles will get filtered out in a few days, as you apparently concede.
