Again this does not differentiate between useful contact and non useful contact. Nor does it make the distiction between finding and making attacking lines (always need to be seeking these), and attachment (don't always need to be seeking this).
What differentiation do you wish for? All contact is useful if being used.
There are only two types of contacts you can get (well more probably but that I care to elaborate on), the first being you hit something. Second being something got in the way of you hitting something. Both are useful, while the second is annoying if you really wanted to hit something.
A term does not need to make distinctions, you want it to perhaps but then it is a wish you need to keep for yourself. Or argue til the world turns over dead on a forum like this one.
There is no 'attachment' without the seeking of it. But the world is not 1 dimensional. You seek one way of 'attachment', it is when your partner seeks something else that more things can happen. The fact that your partner does something should not change the term of what you are doing. That would make you a slave of your partner from a terminology point of view.
EDIT: Also it is just a term, just because you have found a bridge does not mean it is the bridge you seek. Keep searching.
EDIT: To clarify even further if I am unclear. Seeking a bridge is not same thing as seeking ANY bridge. I never said the second. That would be closer to chasing hands.
