The above is equivalent to,

#+header: :var foo=1 2

which due to interaction with some logic put in place to allow the
specification of un-named variables in call lines results in the
following.

#+property: var  foo=1
#+property: var+ 2

#+begin_src emacs-lisp
  foo
#+end_src

#+results:
: 2

#+begin_src emacs-lisp :var bar=1 2
  bar  
#+end_src

#+results:
: 2

Although generally I would say that both

#+header: :var foo=1 2

and 

#+property: var  foo=1
#+property: var+ 2

are mal-formed variable assignments.

This is exactly analogous to

#+header: :var foo="hello" "world"

which raises the expected error
  ``variable ""world"" must be assigned a default value''

the following alternative however works as expected

#+property: var  foo="Hello
#+property: var+ world"

#+begin_src emacs-lisp
  foo
#+end_src

#+results:
: Hello world

Thanks for these examples, the later did brought to light a small
quoting issue which is fixed in the new attached patch.
