Don't tell me magic
I was told in the Air Force when we studied this circuit that it indeed was magic. 
That is if your question really is: upon initial power up for this circuit which transistor will switch on first, Q1 or Q2? And will that always be the case upon each powering up event? Lets let the peanut gallery chew on that one for awhile.
Possible answers:
A: Q1 always.
B: Q2 always.
C: It's always random if either Q1 or Q2 starts first.
D: It can be either Q1 or Q2 but it will be the same transistor starting first for each specific circuit built.
E: Some other magic will decide which transistor starts first.
