I think even if the coating is the same, whether the substrate is cotton or
alpha cellulose (or worse with EEM) seems to make a significant difference.
I think the cotton is more absorbent and soaks up the ink's water base
better.  Note the comment about the higher density of the alpha cellulose
relative to the gsm to paper thickness relationship.  The cotton is simply
"fluffier" and probably has more space between the fibers for the water to
fill.  

The alpha cellulose papers appear to be more susceptible to blotchiness than
cotton papers with what is claimed to be the same coatings.
