It seems to me that you have actually seen some people doing that and has influenced you. It’s an old fashion “make-do” style used by certain people who wanted to make a statement that they were not lower class people (who usually wouldn’t care for lifting the saucer altogether), nor were they gently (who would seem to others as being too feminine or too feeble). However, it was seen by the educated as being, um, red-neck.
Today in China, it is not a popular way of handling the tool. I have seen more people leaving the lid and the saucer on the table than that :-
To me, it is not a safe way.
