Details:

Matlab evaluates the element-wise square and the transpose with equal
importance and thus from left to right:

>> size(ones(1,3).^2.')
ans =
     3     1

>> size(ones(1,3).'.^2)
ans =
     3     1


Octave evaluates the transpose first and then the element-wise square and thus
transposes the scalar exponent:

octave:1> size(ones(1,3).^2.')
ans =
   1   3

octave:2> size(ones(1,3).'.^2)
ans =
   3   1


I don't know which definition is superior, but I would opt for compatibility.
