this can be a good way to be very flexible, but so you don't want/need it 
you can implement this functions with different names in different ways.

you may do this in different files having all functions of one view in a 
file by it's own.
the connection is the normal file class.myextension_pi1.php:

 :
require_once(PATH_tslib.'class.tslib_pibase.php');
class tx_myextension_pi1 extends tslib_pibase {
	:

        function main($content, $conf){
		:
		if ($mode == 1) {
 			$this->displayView1(...);
	 	} else {
 			$this->displayView2(...);
	 	}

	}

	include_once(t3lib_extMgm::extPath('myextension').'view1.php');

	include_once(t3lib_extMgm::extPath('myextension').'view2.php');

}

you can have (nearly) the same names but different implementations

and the two files are like this:
in view1.php:

function displayview1() { ... }
function v1_selectRecords() { ... }
function v1_displayList() { ... }
:

in view2.php:

function displayview2() { ... }
function v2_selectRecords() { ... }
function v2_displayList() { ... }
:

so the includes are inside the class definition the functions of 
view1.php and view2.php are inside the class and share the same class and 
other parameters. In the 'normal' file class.tx_myextension_pi1.php you 
just have the switch about which functions are to be used for the rest of 
page-generation.
