The apply-templates is a no-op; it processes the children of the text node,
and there can never be any. If you remove the apply-templates, you get

Which is the default template for text nodes, so it does no harm to delete the
whole thing,

This template rule does nothing useful because it's the default template for
element nodes.

So you've deleted one redundant template rule and added another redundant
template rule, and the net effect, unsurprisingly, is that your code still
works.
