Hi Gerry,
I suspect that, since the bases of the twin coils are normally
connected together, they should remain synchronized via this
connection. When the bottom current is exiting the base of one
secondary, a significant portion (or even all of the current if you
run with the common base connection ungrounded) will be going into
the base of the other resonator. The current flows into and out of
the bases should help to keep the coils in sync (~180 degrees out of
phase) even after the primary circuit has quenched...
