All this means is that the fragmentation layer needs to take into account the size of the outer encapsulation layers that will be added and make sure its fragments do not exceed 1280 bytes *after* encapsulation. So, e.g., if the encapsulation layer adds an IPv6 header and a UDP header the fragmentation layer should not produce fragments larger than 1280 - 40 - 8 = 1232. If the fragmentation layer does not know the size of the outer encapsulations to be added, it can overestimate and set a safe smaller value (e.g., 1024).
