And this code works? Are you really using the standard erb?
For me (ruby 1.9.3p194), the following template gives a syntax error

<%! if true %>
   true
<%! end %>

Because this is interpreted as

   ! if true
     ...
   ! end

where the first '!' is possible but completely useless here,
and the second '!' is syntactically wrong.

The fact that <%! has no special meaning but is treated
like <% and the boolean `!' can be seen here:

   require 'erb'
   template = <<EOF
   <%! false && (text = 'true!!!') %>
   <%= text %>
   EOF
   puts ERB.new(template).result

outputs `true!!!', because the ruby code is taken to be

   !false && (text = 'true!!!')

and the assignment of `true!!!' to the variable takes place.
The same with <%! true && ... %> gives no output, as expected.
