The post by David Vujic actually mentioned the significant difference - REPL-driven in the way Clojure programmers understand it is not simply interpreting snippets of code in a separate process, but interacting with a running program, including all it's state and modifying it on the fly if needed. Clojure programs listen on a extra port that you can connect your editor to and modify the program as it running. Things like tests and notebooks may run the same code, but don't have the exact state and environment as your running program, be it running locally a staging env or even production. This is not unique to Clojure, a Common Lisp program was famously running on a space probe and REPLed into decades ago, and Smalltalk code is stored in VM images, but few mainstream languages nowadays allow such interaction with a running program
