Hi Avi K.
I am not sure what you are explaining. Perhaps I represented it incorrectly.
I was told there is a time after benching licht, about 20 minutes, where a man can still be involved doing things that cannot be done on Shabbos.
It was during that time that someone saw R’ Feinstein Zatzal, being dropped off. The person approached him later on, and R’ Feinstein Zatzal, explained the situation to him and went on to say that if it does not look right, then it is not right and he wont do that again. Something to that effect..
