Confirmation
Looking around the interwebs, I found a few sources of explanation. Or, more likely, a few variations of one source.
Bonus Round: ANSI
Both the SQL Server 7.0 documentation (two sections above) and Cathy Wissink (section directly above) mention “ ANSI ”, the American National Standards Institute. This is another term that is misused within Microsoft / Windows / SQL Server, and in two different ways (how fun is that!?).

Why does SQL not resolve the collation conflict?
Which is caused by the join condition trying to compare string values where the collation is different on each side of the operator. Because each side of the equals to operator has an implicitly defined collation, SQL cannot resolve the collation conflict and has to raise the error . Incidentally, if one side of the equal's operator had an explicitly defined collation, then this error would not have occurred. See collation precedence later on in this blog.
What is a collation?
Some quick background first though. A collation itself specifies the rules for how strings of character data are sorted and compared. The rules for sorting data vary depending on the language and locale. For example if you was to use a Lithuanian collation, the letter "Y" would appear between "I" and "J" if sorted. And if using the traditional Spanish collation "ch" would be sorted at the end of a list of words beginning with "c". To demonstrate:
What does the "Version" column mean in SQL?
The "Version" column denotes which SQL version the collation was introduced with. This query would lead you to believe that the two collations are the same with regard to the language/locale and you would expect to get identical results when using either collation. But just because they appear to be the same, you shouldn't freely mix them up within your database or instance. For example, if we run the following SQL batch.
