I'm being slightly sweeping in my generalisation, clearly, it is sometimes possible to discern some sort of difference in philosophy.
But the difference is overstated. Both systems rely on three central-ish midfielders, a number nine up top, and two wide players. Whether or to what extent those two can get forward to form a proper front three, or whether they end up having to drop back to cover generally depends more on how well the team is playing and how much of a grip of the midfield they have than on the instructions they're sent out with by the manager.
