One Point/Hip Power
As I understand it, these things are the same thing. I'm not here to argue samatics.
Hips/one point usage in Aikido is very important.
With the whole best defence against a shove thread going on, are attacks that are made further from the hips, eg the head, hard for Aikidoka to deal with. As for example, kote gaeshi, shihonage, kokyunage relie on that power to be effective.... or do they?
