Welcome to the complex world of coyote hunting and calling. Coyotes are super territorial. If you were playing vocals to them, they might of been responding to you. It's hard to know if the vocals you play are inviting or threatening. They may have actually come closer for a look after you left or they may of ran away the other direction. Hard to say.
Best adice I have is to not call same locations more that every 3 or 4 months... so a max of 3 or 4 times per year. Stick to basic prey in distress sounds. Walk in very quietly and behind cover of tree lines or terrain. Take minimum equipment, set up quietly, and wait about 5 to 15 min before starting to call. Once calling is over or even after shooting a yote, wait atest 5 or 10 min before getting up. My first double happened because I sat still after killing one. 6 min later with no calling, another one came out of nowhere and started sniffing the dead one.
Lots more could be said on the topic, I'm sure. Maybe Slim will chime in. He is hands down the resident expert.
