I agree that Shimano appears to have dropped the semi-installed pin after 8-speed. I have a new HG-70 (8-speed) chain and a CN-6600 (10-speed) chain in my parts box right now. The HG-70 has the semi-installed pin plus one spare in the package. The CN-6600 has no semi-installed pin but two full length joining pins in the package.
As to shortening a chain from the wrong end and removing the semi-installed pin, yep it can happen.
