Yeeeeeeeah, I’m not really sure that this “feature” or Meteor adds anything except complexity. But that’s how it was, so I just documented it and made public APIs.
The idea is, let’s say someone borrowed your computer and logged in to their account. Then you open a password reset link. It would be weird if it went to a page where your friend is logged in.
But I think that’s a relatively small edge case. I don’t think this is something we could remove at this point without breaking lots of stuff.
