I didn't know there was a difference but now that I look at it, I think you're right. In Jessie, I had to set this manually in ~/.bashrc because it didn't work out of the box for some reason. Then again, I do not create a directory called ~/bin but instead it's a symlink to another subdirectory inside a subdirectory in my $HOME because of the way I like to arrange things. That probably was why it didn't work for me out of the box in "Jessie"? I'll have to test that in Stretch.
