Fleets pass each other by??

[Hank]

Given:
A moves before B.
A and B have the same number of move points.
Not considering supplies.

Question:
How does A ever intercept B, if B does not want that event to occur?

According to how it is described in the previous Posts, A can only intercept B as follows:

If B does not move.
If A knows the destination square for B (warp point/planet/etc) and A can get there first.

That just seems wrong to me.
