I came across this Winnebago video that shows how the roof is installed (a little after minute 13)
roof
It makes it a little more clear to me how it is done, and emphasizes the importance of keeping that seal in good shape. I also learned it is not a moisture issue, as if the seal leaks water only goes into an aluminum channel - the issue is simply keeping that rolled fiberglass in the channel and not let it pop out under any circumstance.
Not a great design, but manageable if you understand it. Here is the sealant number and type:
Sealant E is a Seam Sealer: Part Number
094401-04-000 is a solvent-based sealer, versus
a silicone or urethane. This product is milky
when applied and becomes translucent when
curing, allowing the underlying paint or gelcoated
fiberglass to show through.
