While the knee-jerk reaction to reading your math post, since you mention birthdays, is to assume you're talking about the Birthday Paradox, I don't think that's what you were trying to report. The Birthday paradox has nothing to do with Chaos Theory, and assuming you are correct in your recollection, 10/365 odds is not the typical number to pull out when discussing the Birthday Paradox; 23 people is the number usually mentioned (being the number needed to reach 50% chance there's a matching pair of birthdays in the group). Thirdly, the Birthday Paradox is looking for a pair in a group, which is a distinctly different situation from looking for your match in a group.
I did a quick search, and I did not find your article. Without reading it, I can't talk to the reasoning or conclusions. It sounds wrong. If your recollection is correct, the odds of bumping into a fellow birthday-haver is 10 times more likely than basic probability should be? That sounds like it should be easily testable, easily noticeable, and would be more well known if true.
Oh, and a final issue with the details you recollect about the contents of the article? People with the same Birthday share the same star sign; if the odds of bumping into someone with the same birthday were 10/365, then the odds of bumping into someone with both the same birthday and the same star sign would be the same 10/365.
As to your dice musings, my answer is no, it makes no difference (assuming the dice are fair). Rolling a d100 for a single event 1:100 versus rolling 2x d10 for a double event 1:100, does not make either one more or less likely than 1 in 100 chances.
(BTW, 20x d5 would not represent a 1:100 chance; individual odds multiply to compute the combined odds, so this would produce 95 trillion outcomes. You'd want to use 2x coin flips and 2x d5 to generate 1 in 100.)
