I'm not sure to see the contention.

A simple example could be you asking your lawyer to prepare a contract for a deal. The deal is sealed but when shit hits the fan you realize the contract had huge holes in it.

Your lawyer is accountable for botching the contract, but at the end of the day you signed it so you're the one having full responsibility.

And we have that in spades in our work: you buy a license for a service, they're accountable but you're responsible.

You are correct, in your example there are two problems and two responsibilities. However, "full responsibility" may not be the right phrase.

1) You will have responsibility outlined in the botched contract.

2) You'll lawyer will have responsibility defending completing a contract with huge holes.

Lawyers don't like suing other lawyers but it happens every day and lawyers keep insurance for this.
