Well, arguably, it is not very believable for a modern interpretation of DP Clark Kent to have his traditionally slicked hair (in contrast to Supes' windswept hair). So to differentiate the two, it made good sense to slick Superman's hair instead. Furthermore, having Cavill's hair as short as in the gif really reduces their options in terms of Clark's hairstyle and how much they can differentiate it from Superman's.
