In our experience (with SolrCloud), if you trigger a full replication (e.g. new replica), you get the "timestamp" directory, it never renames back to just "index". Since index.properties gives you the name of the real directory, we had never considered that a problem/bug. Why bother with the rename afterwards, it just seems unnecessary?
So to answer your questions: 1) Not in normal circumstances, but if replication crashes or stops, it might leave it hanging. 2) No, as long as there is an index.properties file. Not official answers, but that's our experience.
