What’s the difference between water resistant and waterproof standards for mobile devices?

I have a new Nexus 6 that is supposed to be water resistant. Does this have a specific meaning, or is it just an advertising term? I used to have a cheap Casio watch that was also rated water resistant, and I left it on while showering, swimming, etc. for years without any problem. I’m not going to be so carefree with a $550 device, but I’d like to know what I could get away with without causing damage.
Waterproof Phones: IP ratings explained

"IP stands for Ingress Protection and is essentially a rating system developed by the International Electrotechnical Commission or the IEC. The system is now being used to classify different degrees of protection against intrusion or immersion. In other words, when Samsung, Sony or anyone else claims something is ‘waterproof’ or dustproof’ the IP rating will tell you how well it can guard against dust or water from damaging your expensive investment.

The IP rating is usually followed by two digits. The first indicates the level of dust-resistance, the second water resistance. Dust-resistance levels go from 0 up to 6 while water-resistance goes from 0 to 9.

The higher up the scale, the better the smartphone or tablet is at offering protection. So if you have a smartphone that is IP68 certified, that means it’s fully dust-proof and water-resistant, although usually to a certain depth and for a certain amount of time for the latter."
Nexus 6 is rated water resistant, which means it should be ok with some rain or water splashes, but not taking it for a swim.
There are a number of YouTube videos like the one below testing it in a water bath and it seems to be doing fine, though I wouldn’t recommend trying it yourself.
