Because, for an input method simulating some localized
keyboard, the location of a key is important.  For instance,
a user of thai-kesmanee input method expects that he can
input "ด" by pressing a key under his left index finger
while keeping his hands at the normal position on a
keyboard, no matter what key-symbol is printed on that key
('F' in qwerty keyboard, 'U' in dvorak keyboard).

Currently hebrew input method is defined as below:

(quail-define-package
 "hebrew" "Hebrew" "ע" nil "Hebrew (ISO 8859-8) input method.

Based on Hebrew typewriter keys.
Hebrew letters are assigned to lowercases.
" nil t t t t nil nil nil nil nil t)
            ^-->KBD-TRANSLATE

It is defined with KBD-TRANSLATE arg t.

------------------------------------------------------------
KBD-TRANSLATE non-nil means input characters are translated from a
user's keyboard layout to the standard keyboard layout.  See the
documentation of `quail-keyboard-layout' and
`quail-keyboard-layout-standard' for more detail.
------------------------------------------------------------

If your assumption above is true, i.e. the key location is
not important for hebrew input method, it should be defined
with KBD-TRANSLATE nil.

As I have no knowleget about hebrew input method, I don't
know which is correct; it is simulating a localized keyboard
layout or not.
