User parameters are strictly hierarchical
But when checking Update Once Per Iteration it saves before iteration the
variables beforehand
So that second User Parameter will have P as not exists variable and Q as
defined in its own declaration
and therefore:
P1 is saved as ${P} , Q is saved as ${Q}q2
Now User Parameter 1 will update Q = ${Q}q1
and User Parameter 2 will update Q = ${Q}q1q2 where ${Q}q1 is the stored
variable
It sounds like a bug, but this is the flow.
