Thorstein was a former Imperial Legionnaire and Blade who was honorably discharged during the Great War.
In 4E 172, an Aldmeri Dominion assassin attempted to assassinate an Imperial official. Thorstein intervened and was able to kill the assassin, but was badly wounded. Because of his actions, he was honorably discharged and returned home to Skyrim. Due to these reasons, he was not pursued by the Thalmor because he was not present when the Blades were disbanded.
Thorstein rejoined the Blades in 4E 203, when Skyrim won its independence and the reunion of the Blades was made public.
