Show post wont help,, but we should be able to do that using Custom CSS.
Use Main options > Post Specifics > Featured Image > FI Location Excerpts > Beside page/post no wrap
and
Main options > Post Specifics > Featured Image > > FI Alignment Excerpt > Left
Then add the rule below to your theme Global Custom CSS Rule box
.wvrx-posts a:nth-of-type(2n){float:right;}
If it does not do what you want, post back with the rule in place and a link to your page
