Are there 2 Josephs in the story?

The story starts in Luke chapter 1. Joseph is introduced and in some languages depending on how he is mentioned in chapter 2, people might think there is a 2nd person with the same name. How are Bible translations checked to avoid miscommunication before being published?  Here's an example from a Discovery alumni who is now serving as a Bible translation advisor in East Africa.  Note that in this example, the checking process is happening in Swahili from literal word for word "back translations" from 2 other languages: Zanaki and Ikuzu.  There are many other steps in the complete checking process...

OK, there is only one Joseph in the story, but when translating, you have to be careful what you are communicating.
