The Bourbaki dangerous bend symbol is also a part of the lore and symbology for the band. I think that the use of the name is a 'clue' to the meaning of the symbol. The recent new release is the first time I think they've stated this explicitly.

Nicolas Bourbaki is the name of a character in twenty one pilots' concept album

"He'll always try to stop me, that Nicolas Bourbaki He's got no friends close, but those who know him most know He goes by Nico"

It is indeed inspired by the actual pseudonym, not just a pun.

Google twenty one pilots lore explained. There's few hours worth of videos on the topic :)
