I agree with Billy.

The usual gardening practise is to trim away any signs of reversion to
preserve the variety. Bonsai folk may want to consider the usefulness of a
faster growing, more vigorous reversion to the species. These could be a
good source of cuttings or something that you could do preliminary training
on, while still attached, and air-layer off later. You might even consider
lifting the whole thing, as it is, next spring and trimming off all of the
small growth to retain only the new, vigorous leader.

There are always lots of options to think about. :-)

I've been pondering mutations in conifers recently


If the original tree planted was a cultivar (and in this case it would
appear both are) then the variant growth is a revert to the species.
Frequently
cultivars will revert for no apparent reason, but sometimes it can
attributed
to stress of some sort.
Extra low temps, physical damage, drought, or just poor care.
