Seriously? I mean to a certain extent you are correct that it's just an excuse...

But if you really think there is no difference between these two things then you are living in a fantasy world.

Proximity does a lot to encourage socialization between super senior people and super junior people.

Without proximity, it's much easier for either side to put off or brush off things that would be good mentorship opportunities. You don't have to go into work the next day and see your coworker face to face to explain why you ditched them on that pair coding session or whatever it may have been.
