They have the exact same seals though opposite in base mode. Now that Naruto has entered bijuu mode the seals markings are totally different. Now if Minato had an opposite cloak that of Naruto's bijuu mode I would agree. I mean again http://www.mangapanda.com/naruto/644
(Not the same cloak at all)
Again...this is both Kurama's working together
Minato used death reaper seal to seal Yin into himself and 8 trigrams seal to seal Yang into Naruto. Maybe thats why Kurama looks different.
edit: I think Minato has already done the fist bump off-panel
