Well but he had to specialize against Henderson, didn't he? Chael's comin- run bro!
There is a difference though. You can 'theoretically' replicate Hendo's style in training camp. Nothing individually he does very uniquely, but when he puts it together it is a package that you can train specifically for. Unless you can find someone with Vitor's hand speed and charge in speed, it is almost impossible to replicate, so don't waste your time. Instead focus on your gameplan.
