I don't understand well what you want to do here.  But please note
that C-x <left> does not "close" any buffer - it's purpose is to,
maybe only temporarily, show the buffer previously shown in the window
from where you invoke the command.  When invoked with a mouse click it
does not even select that window.  And it tries to show that buffer
with start and point position as shown last in that window.
