Well... your explanation may work well for you. However, you can have 
a two way communication and still be asynchronous -- the term simply 
means that a common clock between transmitters/receivers is not 
required for communication.

So, for a real world analog, I would use -- when I'm talking to my 
wife via the telephone, we're on the same page and know what each 
other is saying -- however, when I'm talking to my mother-in-law, 
it's wasted breath.
