Basic nested tags question

this is a very basic question but i want to make sure i don’t get it wrong. can i nest one tag in multiple places? it seems that when i use the tag bar to tag a tag, that automatically nests the tagged tag w/in whatever i tagged it under. so if i have tag A, and i tag A with B and C, it seems I will have both B>A and C>A. Is that intentional and is there a negative to having it nested multiple places, as long as it’s a unique tag and i won’t get confused? like is it a problem w/in the system?

This is intentional and fully supported, all items having the tag A will have the tags A, B & C afterwards.
