The answer is: Eshell is not a terminal emulator.  It does not
attempt to interpret control characters sent from/to externally
invoked programs.  So, TAB is just TAB.

Now, you can try setting `eshell-send-direct-to-subprocesses' to t,
in which case the TAB will be sent immediately to the subprocess.
If that process handles TAB, then it will provide its own
completion.  This command does not always do what you expect, so it
will require some experimentation.

You can also try adding the command to `eshell-visual-commands'.
This will run it in an "ansi term" buffer, which also communicates
directly with the subprocess.  I use this for "ssh", for example.
