See ?"[" and note in particular "A third form of indexing is via a numeric matrix with the one column for each dimension: each row of the index matrix then selects a single element of the array, and the result is a vector."
Thus the result in this case should be a vector with element 1,3 as its first component and element 2,4 as its second. Of course since x is 2x2 neither of these exist. Thus its behaving correctly.
