yes say you are upgrading from version 6.1 to 6.5.1.1 you would end up running as an upgrade process
altertable-6.1-6.2.php
altertable-6.2-6.3.php
altertable-6.3-6.4.php
altertable-6.4-6.4.1.php
altertable-6.5.php
altertable-6.5.1.php
altertable-6.5.1.1.php
if they are not ran in that order you WILL lose table information.
this should already be run if using upgrade.php the upgrade.php will call each file. IT SHOULD... thats why I don;t trust it and rather run the altertable's myself
