How can the same TCP port show in netstat as BOUND and ESTABLISHED in WIndows?

I’m investigating an issue of port exhaustion in Windows, and the output of netstat shows many ports both as BOUND and ESTABLISHED

...
TCP    10.0.1.9:64318         10.0.1.9:8400          ESTABLISHED     10348
...
TCP    0.0.0.0:64318          0.0.0.0:0              BOUND           10348
...

How could that happen ?
