That is absolutely correct... Back when Arizona was "small" (and had only one NPA), we had 1+ dialing for both 7-digit and 10-digit numbers. Even when we got our second NPA, we still 1+ for 7-digit numbers in the Phoenix area for a while. Finally, Phoenix got two more NPAs, and became a "free calling area", so we no longer have 1+ 7-digits in the Phoenix area, but it still exists in the rest of the state.
Coupled with the fact that if you _do_ dial 1+ before a number that does not need it you get reorder tone followed by "It is not necessary to dial 1 before this number", it's pretty obvious that at least in USWest/Qwest territory 1+ means _exactly_ that the caller is trying to make a toll call (although the charges may be reversed in the case of an 800/888/877/866 call, it's still a toll call).
I'm disappointed you didn't include Mountain Bell in the linage ;-)
In a step-by-step or #5 crossbar office, the "1" would move your call to a tandem office where the LD trunk selection would be made.
