There could be a few benefits to what is proposed in the article, here are my semi-educated guesses.
1. Less dependent on local geology. Geothermal wells are well suited for hot, non-pourous (?) geology.
2. Might be cheaper. It can take years to drill the wells for a closed loop system (e.g. Eavor), less for a fracked geothermal well (e.g. Fervo). I imagine drilling a single borehole for this is way simpler.
3. Less water loss. Fracked geothermal well wells can be pretty lossy (20%?). If water supply is an issue your options may be limited.
