I think in both cases, he was implying the bike is upside down (I've changed tubes this way on front rim wheels with bike resting sitting on the ground, resting on the saddle and handlebars); unless you're implying it's the time the bike spends inverted (a few minutes for a tube change vs. overnight or days in storage)?
