Hover still applies when a touch device is tapped but obviously if the element is a link the page is navigated away from and thus the effect isn't seen. Not all interactions navigate away from the page though so the effects are useful in those cases. And of course, desktop and other devices with cursor capabilities still make use of hover.

While it does still semi-work on mobile devices, frankly it is useless. Trying to trigger hover by tapping on the webpage is just frustrating and overall a bad user experience on mobile devices.
