EDIT: you inserted another post before mine and the latter made me calm down and re-evaluate my answer..POINT MADE SIR.
Yes this thread was not about the encyclopedic definition or the word tone, but rather his generally accepted meaning in the Guitar community.
I personally haven't decided yet wether or not the statement "tone is in your fingers" is true or not, whether Steve was exaggerating when he mentioned EVH trying his rig in steve's studio and sounding "just like EVH", but the satriani Video posted earlier clearly demonstrate that everything is not due to the actual rig/guitar/pickups/amps that you play on.
