ADS1234: Input mux selection query

Hey,

I  was wondering if i could get someone to confirm if i an miss-reading/understanding a table of if there is a mistake in the datasheet available from yourselves.

Table 8-2 "ADS1234 Input Channel Selection With A0 and A1 " shows counting up in binary A1 and A2 selects channels 1-4, however the final row I believe there could be a typo as this shows that channel 4 input positive is selected however channel 3's negative input is selected instead of Channel 4's.

Am I correct in my assumption that addressing A0 and A1 to 1 will select AINP4 and AINN4? 

Thank-you in advance
