We're going in circles here. I've played bass for 52 years and worked as a professional musician for several years as well, even if not for as many years as you apparently have. So I think I may have at least some minor qualifications to speak on the subject of bass playing.
If you want to continue calling the E the "top string," and define "going up" as heading toward the nut rather than the bridge, be my guest. It deviates from the standard used in every single music school and instructional book on bass technique you'll find anywhere. But if it makes you happy to go against the standard definitions, that's fine by me too. However, I doubt I'm the only one here who would take issue with your usage even though I'm sure they (like I) understood what you meant regardless. I was simply trying to be helpful. My mistake for assuming my earlier comments would be taken in the spirit they were given. So I'll bow out and leave you to it.
Onward!
