If you did not reboot and the computer crashed, you could end up with a half installed state just like what happened when I first installed 5.2. FerdFerd also installed 5.5 but had the same problem still until he used the procedure that I gave out. So my conclusion was based on what happened to me and Ferdferd.
If you think the method you used is reliable enough for you then it is all good either way.
