Does Vrykul Drinking Horn reset melee swing timer?

Okay I know there are some things that will reset the melee swing timer such as switching weapons in combat and that it can cause a DPS loss. I wanted to know if the archaeology rare item Vrykul Drinking Horn causes this effect because I have had it bound to Eviscerate on my main just for the cool-factor for a while now and it just occurred to me that I may be losing out on a good chunk of white damage.
