It's a good metaphor. It might be useful if you combine it with the exercise of having people walk carrying a container of water -- something bigger than a glass of water. It's a good way to really become aware of unevenness in your gait, tension in your body (which translates to the water -- I think it's possible to be "centered", in a sense at least, and also so tense that you're effectively frozen in place, because you can't move smoothly). I like it because it demystifies some terminology that, IMO, often acts as an "emperor's suit of clothes", such as "connect with uke" (which, whatever their mystical/ethereal dimensions, have a physical basis and need to be understood as such). Fun to try, anyway, and see what happens.
