antigen update <bundle-name> updates other packages

[trusktr]

Description

The Commands Wiki page says:

antigen update [<bundle-name>]

Where is the bundle name to update. If no is given Antigen will update all loaded bundles (see antigen-list).

however when I supply a <bundle-name>, it still seems to update other things. For example:
