As written there are still some BOUNDARIES (the steel barriers) around the Rendezvous Point. The summary states that the boundaries closest to each trench run were removed (replaced with tape and moved) and the black boundaries in the middle of each alliance’s rendezvous point are removed (replaced with nothing). However the other boundaries are still in place.
Section 3.2 also shows this because the boundaries are still included in the definition
RENDEZVOUS POINT: a 6 ft. 9¾ in. (~208 cm) wide, 12 ft. 6¾ in. (~383 cm) deep, infinitely tall volume formed by ALLIANCE colored BOUNDARIES, ALLIANCE colored tape, and the black BOUNDARY pair that divides the Red and the Blue BOUNDARIES. The RENDEZVOUS POINT includes the ALLIANCE colored BOUNDARIES and ALLIANCE colored tape.
Figure 3-4 also has a fairly clear photo that shows the remaining boundaries and the items replaced with tape.
