They look different (especially side by side)..but there's enough of a resemblance where a cursory glance could make you confuse the two...especially when you are dealing with photos. It happens in real life too...I get confused with people all the time and...again...sometimes the resemblance is close, sometimes it isn't...sometimes it's within a specific context..
Doesn't make it racist though...need more information than that about a person for them to be labeled that.
