Launcher deletes skins only when changing used account

I just changed my Mojang password and looked into the profile settings, so when I had to enter my new password and started the game I had 443 info messages about cleaning the skin:

[15:40:38 INFO]: Cleaning up old skin 10c226db117c68b883399336b59a621d4f9d0f8a4cebef10b040afe9eac867

I don't think this is intended...
