Exactly.  There has been quite some discussion about this feature in the past 
and it can be disabled with /noUpgradeBeforeRemove.
The rationale behind this feature is that this way the admin gets a chance to 
fix e.g. broken remove commands by bumping the revision which ensures the 
package is up to date locally before running its remove commands.  In fact, to 
only fix removal, you could publish an upgraded revision with no upgrade 
commands at all, so the upgrade will merely feed the updated removal 
instructions into the client's local database.

HTH,
Malte
