How can a table be the current table if it's parent database is closed?

I have a routine which lists the current database, current table and all other open databases.

If I open a table and then close its parent database db_current_table still reports it as the current table.

If I select or open another database, db_current becomes undefined as expected and the routine likewise performs as expected: 

procedure db_banner(sequence operation) 
    set_top_line(" ") 
    text_color(TOP_LINE_TEXT_COLOR) 
    current_db = filebase(db_current()) 
    printf(SCREEN, "%s",{current_db}) 
    text_color(TOP_LINE_DIM_COLOR) 
    puts(SCREEN, ":") 
    current_table = db_current_table()    --<<----------------- 
    text_color(TOP_LINE_TEXT_COLOR) 
    printf(SCREEN, "%s", {current_table}) 
    text_color(TOP_LINE_DIM_COLOR) 
----- 
-- snip 
----- 
end procedure

Shouldn't the db_current_table become undefined if its parent db is closed?
