To answer your subject, no, nothing with __ has changed in quite some
time that I can recollect. More information below but I believe you are
misreading the docs.

The SA wiki says: "rules starting with a double undescore are
evaluated with no score, and are intended for use in meta rules where
you don't want the sub-rules to have a score." on this page:
http://wiki.apache.org/spamassassin/WritingRules and yes, the typo
(undescore) is on the web page - thats a cut and paste, not copy typing.
I read this as saying that there is no default score for subrules whose
name starts with a double underscore,
The score of a rule has nothing to do with the arithmetic for meta
operations in determining if the rule is true. Specifically "An
arithmetic meta rule can be used to tell if more than a certain number
of sub rules matched."
In pseudo rule code:
Rule __TEST1
Rule __TEST2
Rule TEST3
Score TEST3 0.05
Rule 4 T_TEST4
meta test (__TEST1 + __TEST2 + TEST3 + T_TEST4 >= 4) will be true if all
4 rules hit regardless of their underlying score math which would be 0 +
0 + 0.05 + 0.01 based on the info above.
So the meta is more of a (hit/no hit) check not a check of the score.
I fixed the typo thank you.
i.e., that given the rules:
body __SUB1 /test/
body __SUB2 /message/
meta USTEST1 (__SUB1 + __SUB2> 1.0)
meta USTEST2 (__SUB1&& __SUB2)
body SUB3 /test/
body SUB4 /message/
meta USTEST3 (SUB3 + SUB4> 1.0)
meta USTEST4 (SUB3&& SUB4)
and a message containing:
==================================================================

Subject: Test message
A test message.
==================================================================
I expected that the meta USTEST1 would not fire while other three rules
(USTEST2, USTEST3, USTEST4) would. When I ran the test, all four metas
fired.
Did I mis-understand the wiki or has something changed in SA since that
wiki page was last updated?
Yes, all four metas should hit. __SUB1 & __SUB2 will be merged (see
below). But yes, the message includes "test" and "message" so all 4
rules will be true.
I use my initials in my rules so I can watch them in a debug situation.
So for example, I added KAM_ to all your rules and created an mbox valid
email from your example above.
As you can see below, there is merger of the duplicate rules and the
meta rules all hit.
