I assume you mean the ON- and WHERE-conditions. Please note that this is also a myth.
The order of the fields does not matter, presence or absence of fields does matter (a lot).
If you have an index with fields A, B and C in that order, you might as well write ... WHERE C = ... AND B = ... AND A = ...
Compare yourself with an example program if in doubt.
