The "Many worlds" or perhaps one should say "many histories" comes as
a consequence of the "Projection" postulate of consciousness. Any
conscious entity has the freedom to choose a projection (ie perform a
measurement) onto a particular basis set. Quantum Mechanics (even the
more general nonlinear version) defines the measure of each outcome of
that projection. Implicitly, the RSSA is invoked to identify this
measure with the probability of the observer seeing that outcome, but
this subtlety is not discussed in the paper. A sequence of such
measurement outcome corresponds to a history.
Thus the interpretation is that the splitting is in the mind of the
observer, not that multiverse actually splits. This is needed, because
different observers may choose different basis sets in which to
perform their measurements.
