Did you read the sentence a little above it?

"We'll demonstrate the messy way first, just to make the concept clear."

And the one a little below it?

"And now the easier method of creating a branch, which we should have
told you about in the first place: svn copy is able to operate
directly on two URLs."

Nothing particularly difficult about managing URLs. I define a shell
environment variable for my project:

export PROJ=https://www.example.com/svn/project1

Then I can create a branch like this:

svn cp $PROJ/trunk $PROJ/branches/1.2 -m "Creating 1.2 branch from
trunk"
