Lua teleporting with less people

[jokoman]

local pos = {
	{x = 1040, y = 987, z = 8},
	{x = 1040, y = 989, z = 8}
}
local newpos = {
	{x = 1041, y = 988, z = 9},
	{x = 1052, y = 988, z = 9}
}
function onUse(cid, item, fromPosition, itemEx, toPosition)
for i = 1, #pos do
	if(getTopCreature(pos[i]).uid > 0) then
		doTeleportThing(getTopCreature(pos[i]).uid, newpos[i])
	else
		doPlayerSendCancel(cid, "There's not enough people.")
	end
end
end

For some reason when using lever it teleports one player alone without checking for second player.
