Yes, but to expand a little Microsoft has a trusted root certificate program that is actually pretty good. Root authorities like Thawte, Verisign, Symantec, Godaddy sell "leaf" certificates to web sites. Microsoft trusts godaddy -> godaddy trusts my website, so IE connects to it for users everywhere without these warnings.
When a site uses a cert that's not issued by one of these vendors and asks you to install a certificate that should be a huge red flag. Instinct should not be to just continue on. Maybe there were girls in the area looking to chat, I dunno, but it's not worth the risk.
Sure certs are stupid, but they are a necessary evil.
And to the OP's question, it's because the site designer has a page redirecting to another page. The second page has the shady certificate, when you click No you don't want to continue it goes back to the first page... which again redirects you to the second page. Kill IE entirely and rethink your internet browsing habits.
EDIT: I prefer Chrome. These issues exist with all browsers, but I'd agree there is some security benefit to "not IE" browsers.
I have to agree, gotten more used to Chrome than Firefox. Haven't used IE in many years.
