Vouchers enable people to do things. Because people are enabled to do x they think they inherently have permission to do so. However, vouchers only provide a means- and have nothing to do with way.

I can vouch that x person said y, but that doesn't mean I agree with them- it just means I provided verification that y was said, so the dialogue can proceed from there (if it does at all). Whereas, if x knows I vouched for them- they may mistake that the dialogue will continue.

Similar examples can be seen in concert/event ticket/voucher sales. Too many links in the chain of events can lead to people getting confused and upset.
