I believe that is because when a terminal starts it loads the existing
contents of the $HISTFILE. (Then, as stated in other posts, it is saved when
the terminal is closed.
But there is a limit to the number of command lines saved in any instance of
bash (any terminal), and when commands exceed that limit, the oldest are
dropped.
$HISTSIZE is the limit in within a terminal, the default is 500 -- setting it
to a negative number makes it unlimited
$HISTFILESIZE is a limit on the size of the command history file (in lines)
