Oh come on, events much rarer than that happen all the time in
duplicate bridge.  Look, the number of possible deals is 52!/(13!)^4, right?
That's 53644737765488792839237440000, if I didn't make a typo in bc.
If just two 28-board sessions are played, you're seeing an event with a
probability that is that number to the 56th power, or roughly 2.67 x 10^1568.
That beats your 10^1240 by 328 orders of magnitude.

The point is, rare events are only interesting if they don't fall into
families of equally rare events -- if they can be distinguished qualitatively,
say.  For instance, staying with bridge, a "perfect deal" would be a notable
rare event; a typical deal is an equally rare event, but not notable.

If conclusions are to be drawn from that number 10^1240, the first requirement
is to demonstrate that this universe is in fact qualitatively different
from the other 10^1240 or so.  If it isn't, the number is a red herring.

(I haven't read the thing Fred was quoting, and if the original author
did in fact put forth persuasive arguments, I retract my implication that
they were being silly.)
