You shouldn't.

Hook_install is invoked when a module is enabled for the first time. 
Right before that, the schema version is set to the latest update number 
in install.inc (or 0 if there are none).

Then later, when updates are added, update.php will pick them up and 
autoselect the right version. So the first update should start with 
version 1.be
