On Beta this was changed, and glyphed gave you the dot, but using it again before the dot expired only refreshed it.
In this sense, you are essentially giving it a 10s cooldown for 5% healing, in which case non glyphed can give you more throughput despite being weaker in efficiency. From my experience, most times you would want to use Ember tap is for a snap heal, not a slow over time one. IMO, Functionally unglyphed works better in most situations you would choose that talent.
