Q: Any reason for this or the order doesn't matter at all?  
A: the order doesn't matter at all. Both horizontal and vertical must be checked. A ship can not be placed if there is not enough horizontal nor vertical space. 

The method, as it is now, can be divided in two smaller methods (one for vertical and one for horizontal) reading two times the matrix. Or it can be done in one pass with an additional column(or row) array. The second way should be faster.
