This line is added automatically when you run tinc init and port 655 is
already in use. In that case, tinc automatically chooses a random unused
port, and adds it to its own host config file so it will use that port
in the future. It also prints a warning when this happens. For example:

$ sudo tinc -n foo init bar
Generating 2048 bits keys:
...+++ p
...................................................+++ q
Done.
Generating ECDSA keypair:
Done.
Warning: could not bind to port 655. Tinc will instead listen on port 28530.

What do you mean by "break"? Does tinc crash? Does it quit with an error
message? I tested your configuration, and it works. It uses the Port
specified in tinc.conf. Of course, if port 655 really is in use already
it will exit with this error message:

Can't bind to 0.0.0.0 port 655/tcp: Address already in use
Can't bind to :: port 655/tcp: Address already in use
Unable to create any listening socket!
