It looks like this (e.g. `#2dcond`) implements a way to directly embed other languages in a racket file [0] and avoids the problems encountered when trying to do it using the `#reader` syntax [1] in a source file. Essentially letting you have multiple readtables in a file (probably not nestable though). I could be wrong about this (need to look more carefully when I have more time), but nonetheless could allow direct embedding of completely alternate syntax with the right setup.
