Yes,

( A~='' or A~=nil ) is always true.
Code:

  A          | A~=''  | A~=nil  | (A~='' or A~=nil)
------------------------------------------------------
  ''         | false  | true    |      true
  nil        | true   | false   |      true
'something'  | true   | true    |      true


Finally, this if is useless.



There should be AND

Code:
  A          | A~=''  | A~=nil  | (A~='' and A~=nil)
------------------------------------------------------
  ''         | false  | true    |      false
  nil        | true   | false   |      false
'something'  | true   | true    |      true
