Cool. If these jackets are the L and XL then they're very much alike. I always thought that the jacket being unzipped quite a bit caused the shoulders to hang lower. Still not 100% convinced that the two pics that you posted show two different jackets, but if they're really alike the differences can become quite subtle.
Also, do people really put their jackets into washing machines?? Yikes!
I'd say, just wear it naturally and rub it with your greasy hands every now and then or if you want to speed up the process wax it. Or just wax it lightly.
