Under heavy load, the application might not be serving the
desired pages. If there are not verification checks, the
transaction will still PASS without allowing us to get an
idea into the application problem. For e.g., if an
application serves a different page or error that doesn't
fall under the regular HTTP error codes, we might miss it
without any verification checks.

When I was working with one of the HTTP based application, I
observed the transactions getting passed in the controller
while failing with manual user.
After analysis, I found that the application serves a simple
HTML page with the message "exception found". LR didn't
report any error since from its perspective it is a valid
HTTP 200 response. Adding a verification check helps you to
uncover these kind of RUN TIME errors
