No, you said this of them as well:

But that principle does not even hold for WM's own diagrams, like

1 2
1 2 3
. . .


2 1
3 2 1
. . .

In which no line can contain all members of all lines
because only a last line could do that, but there is no last line.

But every one of those infinitely many lines is a proper subline
of its next line, with no last line ever containing everything.
