No.... think real life for a minute. Stand right next to someone, holding hands. You are 0' feet apart, right? You MUST be, as you are actually touching. And yet, to move to the spot they occupy you must travel a couple of feet or so.
The distance apart you are is how far you must move to be adjacent, not how far you need to move to be in the same space.
Let's try another real-life analogy. Put two 5' long tables together (so that the result is 10' long) How far apart are they? Answer: 0' apart, though we must move one of them 5' if we want it to occupy the same space as the other.
"Apart," by definition, is the amount of space BETWEEN objects or people and has really nothing to do with the concept of reach, etc.
