Yes, I think you got it.
The one thing not noted is the outlet between the timer defeat and the
timer. It just passes the current through to the timer, but if the hot
is provided by the first switch, could that back feed the timer in an
undesirable way?
I'm at the point of thinking there is a small short somewhere. But in
all respects it doesn't add up. Here are my "test results":
1. The main switch works the lights as expected when the second feed is
disconnected (completely unplugged, or GFCI is tripped).
2. If the second feed is plugged into the GFCI outlet (removing the
timer from the equation) and the timer defeat is OFF and the main
switch is turned ON, the GFCI trips.
3. Using the GFCI as an outlet to an unrelated load (skill saw,
worklight) works as expected (the timer defeat also works). Lights work
as expected from main switch.
4. Turning main switch OFF and providing the current to the lights from
an outlet on another circuit works as expected.
4a. Turning the main switch ON blows the breaker for this circuit AND
the one for the other outlet. (This was probably not the safest of
tests, now that I think about it).
I hope this gives a bit more insight.

I need to install parallel switches to a couple of lights. And so you
don't think I mean a common 3-way switch, I want this behavior:
Both on: lights on
A on: lights on
B on: lights on
Both off: lights off
This is just (A OR B) logic.
I can't quite visualize your description. Here is my attempt to draw
it: (fixed font suggested)
------------------------------------------
| |
X switch X timer
Hot (black) | | to
----------------------------------X timer defeat load
Neutral (white)
-------------------------------------------------------
Ground (green)
-------------------------------------------------------
Is this what you want?
