Why would a priest not want to "transfer holiness" to the people in the courtyard?

I find this passage to be confusing. Maybe I don't understand what the "transferring of holiness" really means. This verse implies there is some sort of danger in the transfer of holiness to the people in the outer courtyard. Does this have to do with the priests only being able to be this intimate with the presence of God?

Ezekiel 46:20

NLT - ²⁰ He explained, “This is where the priests will cook the meat from the guilt offerings and sin offerings and bake the flour from the grain offerings into bread. They will do it here to avoid carrying the sacrifices through the outer courtyard and endangering the people by transmitting holiness to them.”
