Would the following work instead of its respective other?

  
if (type(t1) or type(y2)) ~= "table" then 
  
--instead of... 
  
if type(t1) ~= "table" or type(y2)~="table" then 
  
--be the same? 
  

and..

  
if method ==("ceil" or "floor") 
--instead of... 
if (method == "ceil" or method == "floor") 
--be the same?

The LUA users wiki states it pretty well:

If the first argument is not false or nil it is returned, otherwise the second argument is returned. So, a boolean is only returned if the first argument is true or the second argument is a boolean.

So as far as your first snippet of code goes, only the second one would work properly.

Also, for your second snippet of code, only the second would work properly.
