[blml] L93 Why "Director in charge"?

[Robert Geller]

In ordinary talk by bridge players, all directors at a tourney, both the director
in charge and his assistants, are called "directors" but, as everyone on BLML
knows the Laws reserve "director" for THE director (the guy in charge), and
everyone else is an "assistant" (see L81D)

A search of the 2007 Laws shows that the word "director" is used 242 times.
In 236 of these case the usage is consistent, just the one word "director."
However, for a reason I don't understand (I'm hoping someone here can explain
it) suddly in L93 (throughout L93) the phrase "Director in charge" is used 
(see example below).  This phrase is used six times in L93 (and only in L93).
******************************************************
LAW 93 - PROCEDURES OF APPEAL
A. No Appeals Committee
The Director in charge shall hear and rule upon all appeals if there is
no Appeals Committee (or alternative arrangement under Law 80B2(k)), or
if such cannot operate without disturbing the orderly progress of the
tournament. 
<SNIP>
********************************************************

According to L82D, the Director can delegate any of his duties to an 
assistant (while remaining responsible for performance of the duties).
Therefore, even if L93 assigns appeals-related duties specifically
to the "Director in Charge," he is free (under 82D) to delegate these to
an assistant (in the absence of a specific provision to the contrary in L93,
which of course doesn't exist).   

So, why does L93 (and L93 only) use the term "Director in Charge"?
Can anyone explain this?

And how should we translate this?  Should we take seriously the difference in
usage between  "Director in Charge" in L93 and "Director" everywhere else
in the Laws and translate this differently from the translator used for
"Director" in L1-92, or should we assume this is just one more instance
of shoddy and inconsistent wordsmithing by the WBFLC?    (My money is
on the latter, needless to say, but if there is a real difference could someone
please explain this.)

Thanks.
