Personally I interpreted the remark differently. But it also may depend on the field you are in.

First, publish the idea, the rough concept. You can get valueable feedback from this.

Second, publish an implementation of the idea and the evaluation thereof. This is the actual result.

Depending on limitations it can be worthwhile to publish an extended and revised version of the second one. You can go in excruciating detail on this and include unremarkable side results.

Depending on your field you might be limited to 8 pages for your second publication, which is often very limiting, or your third publication might be your thesis linking several results together.

Version control would be nice though. Especially when you notice errors yourself you would like to fix.
