In reality the example would look like follows (assuming 4-space-indentation but the problem is the same for other indentations):

That is perfectly fine too. I don't find this style confusing. The 2nd, 3rd and 4th lines are stripped of their indentation according to the closing delimiter. And that is it.

I think it is a good thing to have the option to start the line of text immediately after the opening delimiter or on the next line.
