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...

I do believe that the primary keeps them in "proper" phase when
sufficient energy is still in the primary. My question was
addressing what happens once the primary quenches (should be at
maximum energy in the secondary). I'm thinking that phase drifting
begins at this moment in time if not before. I guess I'm assuming
these two coils are side by side and not a bipolar coil. Even with
a bipolar coil, if the center turn is grounded, I dont know if the
magnetic coupling will keep them properly phased. Maybe Antonio can
shed some lite on this.

Like you say, the series connected primaries force the secondaries to stay
about 180 degrees out of phase with each other and at the same frequency.
Once the secondaries have discharged and are ringing down, they probably do
exhibit relative phase shift, although there is still some fairly strong
electrostatic coupling between the two top loads until the voltage dies off.
But so what if their phase wanders during the last part of their ring-down.
The next "bang" from the primary jolts them back into the proper phase to
unleash connecting leaders again.
