To clarify even further:

if var == 1 or 2 or 3 then
   -- do X
end

Is functionally identical to:

if var == 1 then
   -- do x
elseif 2 then
   -- do x
elseif 3 then
   -- do x
end

It is NOT the same as:

if var == 1 then
   -- do x
elseif var == 2 then
   -- do x
elseif var == 3 then
   -- do x
end

If you want to do that third thing in one go, you need to write it this way:

if var == 1 or var == 2 or var == 3 then
   -- do x
end
