The braces are matched but the \N at the start of the regular expression
is not. The missing ending \N means that everything (including the
closing braces) is taken as part of the regular expression, so you
effectively have:
"${if match {$bh_received:}{\N<opaque regex>"
and the string just ends on the parser without it seeing the necessary
closing }'s.
