Teflon tape on the threads of a hose connection does absolutely nothing. The hose seal is two flat surfaces being squeezed onto the rubber washer between them. If the washer is leaking, Teflon tape won't hold the water in. In addition to the water leaking out through the threads, where your Teflon tape would be, it also leaks out the back side of the hose nut. That is open also.
huh... I guess I have been lucky for the last 56 years as almost always does teflon tape work for me,.... in fact, I just added some to my "Y" connector this past trip due to a small drip....
and obviously speaking, that is as long as the washer is in good shape as well.
Do what works for you. It certainly can't hurt anything. But, if I had to guess, I would say that when you put the Teflon tape on the threads, it lubricated the threads of the hose connection which allowed you tighten the connection down more, sealing the connection with the washer better.
