"pass and repass" is a legal phrase.
If there is a right to "pass and repass" then someone can walk along the
path or road in either direction more than once. In some circumstances
it is permitted to drive a vehicle along a road where there is a right
to "pass and repass".
I am not a lawyer, but my understanding is that "repass" is included in
the phrase to make clear that the right is to pass in either direction
any number of times. "pass" on its own could be interpreted to mean
"pass just once".
Also a right to "pass and repass" does not include a right to stop on
the path or road.
