Well - this is the way how PHP works. The interpreter will just output
all the stuff between ?> and <?php without interpreting it.

This works in all cases. In fact this is by design, how PHP works.

It depends on the situation. Usually it's easier to embed large HTML
fragments than to output every single line using echo or print.
