Yes, but the user is attempting to use the main page column tags on a page other than the main page. That is why it isn't behaving as expected by Minion3665. From the OP, it appears that Minion3665 wants to achieve a layout similar to the homepage and is attempting to do so by using the main page column tags. My point is that a regular article page has the rail which takes up the approximately 300 right-most pixels. Then the right column tag takes up the next 300 right-most pixels and the left column tag takes up the rest of the page. This is in contrast to the main page which does not have the rail and thus a larger portion of the left column. In short, the tags are actually working just as they are supposed to. The real issue is that, since article pages have the rail, use of the main page column tags results in two columns approximately the same in width rather than two different widths as it does on the main page.

This may or may not be considered a violation of the customization policy. However, the following could be used in the wiki-wide CSS to hide the rail for that particular page. This should probably be tested using personal CSS just to confirm whether or not it covers everything needed to expand the page out the extra width.
