Not at all. In any situation you might be grappling or you might be protecting against an attack and you automatically register that you can do 'XYZ'. It doesn't matter where it came from but the context of your situation might see you perform more like a practitioner of one or other of the styles. For example if I was totally relaxed and in control of the situation I might be more like an Aikidoka. A bit more stress or physical duress may see the emergence of the Karateka and display a few more powerful strikes. In a totally stressed out multiple attack situation and I think you would see more evidence of the Krav training kick in.and you find there is never any confusion of technique in what comes instinctively to you in a situation having such a mixture of differing technical responses?

Within the training environment I have no problem differentiating.
