When have a parameter with a single braces at the end of the parameter, the braces does not go to the parameter:

{{template|1={text}}} get parsed as {{template|1={text}} } (parameter 1 is {text) not as {{template|1={text} }} (parameter 1 is {text}).

Adding a space behind the closing braces is the only way to avoid the wrong parsing.

In my opinion the preprocessor should respect balanced single braces, so the example get parsed better.
