No, I got that part. That's true in any first-past-the-post system, and especially true in ones with more than two major parties. (The solution to that would be proportional representation rather than first-past-the-post.)

But the complaint seemed to be, not that it kept happening, but that it kept favoring the Conservatives. So, on the one hand, the fact that it keeps favoring one party is an issue. On the other hand, the way the complaint was made makes it sound like it's not coming from a position of objectivity.
