A new feature or a Bug?

iOS and iPadOS

I am not sure if this is a bug or a feature still I do find it annoying. I use my iPad Pro 2020 with content with mainly two languages; English and Arabic.. I found that Alex voice comes from the left hand speakers and the Arabic TTS comes from the right. This is very confusing. This is only when I use the built-in quad speakers not with connected headphones either wired or bluetooth.
