Yet the subject is not completly closed, as the end of line expansions
are different:

Leads to, in dvi:
Hello uu +
vv
.
Hello x
x +
yy
.
And with makeinfo in C (or texi2any):
Hello uu + vv.
Hello x
x + yy.
Oddly, if not in @example, the results are the same
Hello uu + vv. Hello x x + yy.
This means that TeX does something odd with the newline after yy, as
a plain
Hello x
x +
yy
.
leads to
Hello x x + yy .
So the newline after the yy appearing when expanding in @example is
eaten when expanding outside of @example.
That being said, this is a different subject, and is also covered in the
manual by:
* In general, the interaction of newlines in the macro definitions and
invocations depends on the precise commands and context, despite the
previous statements.
