well nit, i think you are correct, there is a period of a few weeks in the course, where you study subjects from other faculties, not the gen -eds, for example you can study a language. However there are some limits, they try and make sure that you don't take subjects similar to what you're studying in med, like in some cases they won't let you do pharmacology
but it is my understanding, that you only do a subject for a short period of time, nothing greatly significant.
i'm 99% sure about this, since i asked the acting dean about this all on the info day [cos the faculty advisers said that there was no such thing, wheras on the website it clearly stated it] and he said i was right, that you can study subjects from other facutlies, but yes, there are limits.
best to ask the dean or someone in the faculty about it, who actually knows what the course is [as opposed to the idiots that were at the open day] about it
further to the above "Students are also required to undertake 12 UOC of elective courses in a faculty or faculties other than Medicine." is what it says on the website.
