Found this useful explanation in the split-stream encoding white paper:

if operations with similar encoding
requirements are assigned to the same stream,
then the bundle or operation formats can be
tailored to each stream, saving instruction space
and likely reducing decoding difficulty. For
example, all operations with an effective-address
parameter (including loads, stores, and branches)
can be assigned to one of the streams, so the logic
to decode an address is not needed in the other
decoder.
