This seems badly named, or badly described. A vehicle that goes from A
to B, then returns along the reverse route to A, is said in British
English to perform a "round trip".
A vehicle that completes a (approximately) circular route to arrive
back at its starting point is NOT called a "round trip", whether or
not it performs that circuit just once, or multiple times.
