else in csh

[Stephen [Steve] R Smoot]

Can someone explain to me why the following is valid in csh?
It seems invalid according to the man page (though treating the 
commands listing as a formal grammar is going a tad far, I know),
but runs without error:
-------------------------------------------------------------------------------
#!/bin/csh -f
else
	echo "No, I dont get printed, never get executed"
endif
-------------------------------------------------------------------------------

It makes invalid nested if statements easier to write than most
languages...
