Originally, contextual alternates were made for the construction of ligatures and calligraphic scripts, then they were repurposed for a pseudo-random effect. But if the essence of contextuality is in providing two or more different appearances for the same character, why not go all out and throw opposites together, fluency be damned! Hence Scotch Biplex—roman and italic in the same font. But strangely, it’s not too hard to read… 

In Scotch Biplex, there is a rigorous application of extreme stylistic contrast, mixing the Roman and Italic of Shinntype’s Scotch Modern. This genre seemed to be the best bet for alternating roman and italic, with the very obvious disparity of construction (not least the 20° of slant difference) balanced against the even colour provided by both the similarity of widths between the component styles, and the enormous pot-hook serifs of the italic lower case, which fill out the mid-x area. Notably, the angle of italic slant matches the roman diagonals, as can be seen in the title of this post. It was meant to be!
