Retirement tax questions

Right, that comports with what I've seen online. However, based on my discussion with the other guy further up the thread, the following two scenarios may differ:

 

Scenario 1: I have a 401k holding only Roth contributions and earnings, and I take a $50,000 loan from it, repaying it in 5 years with an additional $10,000 in interest, and then rolling as much of it as I can into a Roth IRA without paying taxes on it (and the rest, if applicable, into a traditional IRA).

 

Scenario 2: I have a 401k holding only pre-tax contributions and earnings, and I take a $50,000 loan from it, repaying it in 5 years with an additional $10,000 in interest, and then rolling as much of it as I can into a Roth IRA without paying taxes on it (and the rest, if applicable, into a traditional IRA).

 

So my follow-up question would be: Is the amount rolled into a Roth IRA a) the same in both scenarios or b) different in each scenario. Additional questions: Was anything rolled into a Roth IRA in Scenario 2? Was anything rolled into a Traditional IRA in Scenario 1? (Note: If the answer to the first question was a), then one of these two answers must be yes)
