They would be randomly sampled if, godlike, some third person pulled them
out of the ensemble of all possible observer moments - and in that case, it
certainly would be surprising if these three turned up one after the other.
However, from the first person perspective, they don't need to be "sampled"
at all. It suffices that these three OMs simply exist somewhere in the
plenitude, and - by definition - there will also exist an observer who
experiences (at least) these three states.
The situation is slightly different if there is more than one OM that would
fit a particular state. For example, if there are two distinct OMs that
would fit into the sequence as <N + 4>, then at that point the number of
observers doubles. For the single observer just before the duplication, this
would be seen as a 1/2 probability of experiencing one or the other state.
