you are running NOS on the inlet plenum somewhere so don't want to ignite that mixture if it fires when an inlet valve is open
Nitrous makes no difference to that, could still ignite the inlet mixture anyway if it was just fuel and air, in fact the nitrous if anything makes it LESS like to fire in a lot of circumstances, although if it does fire, it will do so more dramatically.
Its not just that that is the issue though, its that when it fires you could be 20 degrees later than the inition curve was set for, and hence cause massive detonation in the engine that cycle!
