Help with smn lua, debugging, interpreting print commands

Hi.  

I'm trying to interpret some print commands I got when trying to debug my smn lua

I have the following code 

function pet_change(pet, gain)
	if gain then
		print('summoning')
		if pet.name == 'Odin' then
			print('summoning odin')
			equip(sets.avatar.odin)
		elseif pet.name == 'Alexander' then
			print('summoning alex')
			equip(sets.avatar.alexander)
		elseif pet.name == 'Atomos' then
			print('summoning atomos')
			equip(sets.avatar.atomos)
		elseif pet.name:match('Light') then
			print('summoning light')
			equip(sets.spirit.light)
		elseif pet.name:match('Spirit') then
			print('summoning spirit')
			equip(sets.spirit)
		elseif buffactive["Avatar's Favor"] then
			print('summoning avatars favor')
			equip(sets.avatar.favor)
		else
			print('summoning general')
			equip(sets.avatar[avatar_mode])
		end
		disable('main', 'ammo')
	else
		if not tp_lock then
			enable('main', 'ammo')
		end
		equip(sets.idle)
	end
end

When i summoned garuda, i got 4 lines of print commands:

summoning

summoning general

summoning

summoning general

Why did it double up?

When i had garuda assault something, it did:

summoning

summoning general

I will admit, its been a very long time since i made this lua so a lot of the logic i've forgotten.  I thought this stuff was for when i summoned only, i'm not sure why it did it when i had garuda attack something, and same after i did a bloodpact (summoning & summoning general), so maybe i need a refresher on what pet_change(pet, gain) means  

Can i get some help?  Seems I need to figure out this before it drives me crazy, and then see what other things happen and ask about them later.
