octave:18>  size(foo)
ans =

    8192      1

A matrix with 8192 rows and 1 column (i.e., a column vector)

octave:19>  size foo
ans =

    1   3

A matrix with 1 row and 3 columns, i.e., the string "foo".

It seems that if you use "size" without the parenthesis it interpretes the argument as a string...
