After 30 years plus in this business, I have to say I have never heard of this before. I am sorry but to try to imagine someone who is not in the best of moods in the first place, having the patient of pouring 4L to 6L through a, up to 1/4" hole, should have been filmed and submitted to AFV.
Please do not take offence here as we have all done some funny things through our life.
To answer your question, providing it was the dipstick to the oil pan, you are fine. If not, then get your vehicle to your mechanic now. Your smoke issue has probably gone away which indicates you most likely spilled oil on the engine and it simply burned off as the engine heated up.
