Can only one triggered planet modifier be active at a time?

[Red Death]

I've got something like the following on a planetary deposit:

popgrowth = {
    icon = "unused/d_alien_propaganda"
    is_for_colonizeable = yes
    category = deposit_cat_food
    should_swap_deposit_on_terraforming = no
    drop_weight = {
        weight = 0     
    }

    triggered_planet_modifier = {
        potential = { free_housing > -3
        }
        planet_modifier = {
            planet_carry_cap_add = 1000000 
            planet_amenities_add = 10
        }
    }
  
    triggered_planet_modifier = {
        potential = { num_pops < 10
        }
        planet_modifier = {
            planet_immigration_pull_add = 100
            planet_amenities_add = 11
        }
    }     
}

(amenities are just there for easy checks)

However, it seems to me like when both triggers are met, only whichever I place first becomes actually active. Is this how it is supposed to work?

I figured out the solution myself: Don't use planet_modifier if you want the triggered modifiers to add on to each other. So that would be:

popgrowth = {
    icon = "unused/d_alien_propaganda"
    is_for_colonizeable = yes
    category = deposit_cat_food
    should_swap_deposit_on_terraforming = no
    drop_weight = {
        weight = 0     
    }

    triggered_planet_modifier = {
        potential = { free_housing > -3
        }
        planet_carry_cap_add = 1000000 
        planet_amenities_add = 10
    }
  
    triggered_planet_modifier = {
        potential = { num_pops < 10
        }
        planet_immigration_pull_add = 100
        planet_amenities_add = 11
    }     
}
