OK, let's say one way to detect spam is to identify patterns are
common in spam messages.
With that in mind, the reason it was recommended to send both
formats in one message (aka "multi-part message") is that many
spammers provide *only* an html version. Thus, by providing a
multi-part format your message is less like a spam message.
Likewise sending an html message with the <title>Untitled
Document</title> will also likely score you *bad* points with some
filters. Why? Well mostly because it is commonly found in other
spam. For a list of tests performed by SpamAssassin (a commonly
used spam filter) see: http://au.spamassassin.org/tests.html
And yes the whole message could still be "blocked" by the spam
filter.
There are other reasons to provide both text and html format. Some
mail servers strip out html (many large corporations), so if you
have not provided the message in an plaintext format, then users
will potentially see a jumbled message. And some people prefer
plaintext.
