It is possible for users to put in the same tag again if the case is different eg t/tag t/Tag. This may cause unintentional duplication of tags if the user is in a hurry and types the same thing twice
Steps to reproduce
Ensure that no student with name "Tester" is in the app. You may replace the name with anything else.
While the team may argue that this is allowed and is actually a feature, I think a reasonable user may expect that this is handled. Either ways the user should get a warning when the command is executed or note in the UG that this is allowed and they should be careful.
