4.5.2. The main usage of the future perfect form
The future perfect form (FuPF) is the future of the present perfect form (PrPF), and sees the anterior event from the future. See the following examples.
a. I will have finished the work by the time my boss comes back.
b. They will have been the champions four times if they win the final game.
c. We will have been living here for fifteen years next November.
If the above is considered as the usage of PrPF, (39a) is Perfective and Resultative, (39b) is Experiencial, (39c) is Continuous. When (39a) is taken as the sample, "by the time my boss comes back" is parallel to M, and then s/he finishes the work before or at this time.
The point of M is determined in view of S, and then E is put, E is anterior to M. It means the speaker looks the future event from the more future. See the following figure.
If (39b) is taken as the sample, "if they win the final game" is parallel to M, and the speaker imagines E of the four times from here. (*23)
