I mean, I might well be too naive about this. If the underline is
occuring in a fixed position with regard to the baseline, there are only
a few obvious avenues to have multiple underlines work:
a) change the baseline. That's not really acceptable when mixing
underlined and non-underlined text
b) change a property (akin to offset but probably unique to \underline
to avoid unexpected interactions) for the sake of additional
underline calls. That would result in the _innermost_ \underline call
ending up lowest.
c) somehow affect bounding box/outline in a manner that can be
interpreted for moving the whole next underline to a different position
while retaining the baseline. That's sort of the handwavy "do magic"
option that may or may not be workable at all.
