10 conventional loan limit when working with a partner

[Clark Kongs]

If i am partnering with someone 50/50 (buy and hold strategy) and we put both of our names on each mortgage does that mean that we are limited to 10 conventionally financed properties combined as opposed to 20 if we were working independently?  I have read the information from fannie mae and it seams contradictory. The part i am hung up on is where it says -"the financed property limit: is cumulative for all borrowers"  Thanks in advance.
