Yes it does present a problem for someone who doesn't have credit cards or extra credit to extend for travel. I didn't say it was a requirement though. Keep in mind that what I wrote are guidelines. (Trying to keep it real for the Flyertalkers.) I'm sure something could be worked out if needed but it may be an extra hassle in adjusting to the job. I thought a lot of consulting companies had their employees front their own expenses (even with company-issued credit cards) but I guess it's a smaller number than I thought.
