Hi,
If I am not wrong then your need is
page set for primary [Always start on Odd page]
page set for secondary [Always start on Even page]
if this is the case then
On the basis of your chapter match you can create 2 different page sets and that can be picked up when the certain condition will arise.
That means
1] 1 page set for primary
2] 2 page set for secondary
I think this can help you
cheers,
Mahesh
