ADV7188 ADC capacitor network

Data sheet for ADV7188 Fig 52 shows 10uF polarised capacitors across CAPY1 and CAPY2 with "+ terminal" to CAPY1, and across CAPC1 and CAPC2 with + terminal to CAPC1.

ADV7188/4 Evaluation note (EVAL-ADV7188/4 Application Note August 2006) Figure 4 shows an ADV7184 and similar network except that the 10uF capacitor "+ terminals" are to CAPC2 and CAPY2.

 

Why the difference, and what is the correct polarity of the 10uF capacitors?
