I've noticed in classes with multiple templates that ERB variables seem
to share a single scope. That caught me by surprise-- is that intended

Intended or not - that is the behavior, and this is Ruby so it is
possible to mutate things that should be immutable.
There is great responsibility when writing code in ERB because of the
generality and power available in Ruby. Suggest using EPP instead where
problems like this one does not occur.

Here's a simple test case:
class erb_scope_test (
)
{
$myarr1 = [ 'one' ]
$myarr2 = [ 'two' ]
$str1 = inline_template("<%= @myarr1.concat(@myarr2) %>")
notify { $str1: }
$str2 = inline_template("<%= @myarr1.concat(@myarr2) %>")
notify { $str2: }
}
Notice: ["one", "two"]
Notice: ["one", "two", "two"]
