I and several other pointed this fact out many years ago.
Had he just stayed in Sweden and faced the music, he would have gotten less time than 6 years, or maybe no time and then tossed from the country.
Instead he was on bail for longer time than he would have gotten, and definitely less time than he spent in the Embassy.
In fact one of the ironies is that some of his fans argued that his time in the Embassy should count as jail time.
