Using relative odds as a definition of changes in proportions would
mean that your example of a 30%-units increase from 1% to 31%
would, for example, be poroportionate to a 73%-units change from
10% to 83%. Both would have the same odds ratio = 44.
Equal differences in percentages means that the same proportion of
the population changed their minds.
The meaning was probably "proportionate" = "of the same order of
magnitude".
