Is a debt past SOL and removed from your credit report considered legally satisfied?

No, the expiration of the SOL designates the time in which the creditor has to file a lawsuit. This does not mean a creditor will not pursue litigation, as an SOL is not an "automatic" defense in creditor vs. debtor suits. If a debtor is sued after the expiration the debtor must bring forth proof that the debt is invalid, the court will not do this for him or her. Often people receive a summons for what they believe is an invalid lawsuit because the SOL has expired, this is not necessarily true. A creditor may file a suit one day before the SOL expires and it will be seen as valid litigation. In addition, a debt is always valid until it is paid, settled in a lawsuit or discharged in bankruptcy.
