IMHO this is bad advice. IMHO, ideally you should start with however many strings you will ultimately use. Of course no one can see the future, but it sounds like you are already established on the 6. Unless you have some pressing reason, I suggest continuing on the 6.Thing is, we usually tell people to start learning on a 4 before going to a 5 or 6.
Why I think an incremental approach is bad advice. IMHO learning 4 and then switching to 5 or 6 is not an incremental change. The number of strings has an impact on the logic you use to navigate the fretboard. Ideally you should know the fretboard cold, and fingering and shifting should happen automatically. Whenever you change the number of strings, I believe most people will need to update their mental map of the fingerboard. So basically in order to be really fluent on a 6 you have to tear up your 4 string map and vice versa.
Don't get me wrong, this is something that can be managed. So if you have a good reason to switch between 4, 5,and 6 it can be done. But IMHO, the required versatility is not free. It requires you to give up a bit of extra fluency you can build if you play one instrument exclusively.
Whether this is significant can vary depending upon the processes you use to learn and maintain music. I find it makes a bigger difference whenever I think in terms of note names and/or reading music notation or chord changes. When using this type of logic, I find the physical references on the fretboard are very import. I find it makes a much smaller difference when I think in terms of intervals and patterns, and/or play primarily by ear.
My experience. I was a full time pro for about 18 years. I started with 4 and transitioned to 5 and then later 6. Both of the transitions were fairly long and arduous for me. I would say doing the transitions knocked my progress back about 2 years. If possible it would be best to avoid having to overcome the related difficulties. I would say it took about a decade before I really started feeling like a naturalized 6 player. Before that, I felt more like a 4 player with a couple of extra strings.
At this point I am most at home on the 6, and tend to stumble more when I pickup a 4 or 5. If I play a 4 or 5 for any significant time, it starts to rewrite the automated processes I use to play the 6, and degrades my fluency. This occurs with < 1 hour playing a 4 or 5. So I choose to play the 6 almost exclusively, even if I don't need all 6 strings.
I do switch between BG and upright bass. I seem to have totally separate mental maps for these two instruments as they require different logic for shifts and fingering. Initially I used Simandl fingering on both BG and UB, but about two years into being a pro, I transitioned to essentially one finger per fret on bass guitar.
The one challenge will be finding someone who is able/willing to teach you on 6. Also finding material specific to the 6 will probably be challenging. Even with these detractors, I would prefer to learn on the 6. Learning might involve expanding material you are tasked to learn so it is relevant to the 6 string. For example if you are given a set of written arpeggios or some other sort of reading exercise, you might write out extra arpeggios that fall in the range of the low B and high C.
