The following code does what I want:
\blank
\SetTableToWidth{\textwidth}
\starttable[|lp(0.90\textwidth)|]
Some text \SR
\SR
\HL
\SR
\HL
\SR
\HL
\SR
\HL
\stoptable
\blank
I would think that the following code is equivalent:
\blank
\SetTableToWidth{\textwidth}
\starttable[|lp(0.90\textwidth)|]
Some text \SR
\dorecurse{4}{
\SR
\HL
}
\stoptable
\blank
But it is not. I get:
Underfull \hbox (badness 10000) in alignment at lines 39--49
[][][][][]
! Misplaced \noalign.
\TABLEnoalign ->\noalign
\bgroup \let \noalign \relax \let \next =
\insertTABLEtail ->\TABLEnoalign
{\global \settrue \preventTABLEbreak \globa...
\stoptable ->\chuckTABLEautorow \insertTABLEtail
\TABLEnoalign {\globalletem...
l.60 \stoptable
and h gives:
I expect to see \noalign only after the \cr of
an alignment. Proceed, and I'll ignore this case.
What am I doing wrong?

The correct syntax is \NC ... \NC \SR but that doesn't solve the problem
in this case.

Table and expansion are tricky. The error is caused by the last \HL and
goes away if you add another line.
But if you only want four horizontal lines, why not use \thinrules
\thinrules[n=4]
Also have a look at m-educat.tex (look at the example in the end of the
file) which is essentially a fancy wrapper around \thinrules.
I don't know if \thinrules are documented in a manual, but pack-rul.mkiv
gives a few examples:
\starttext
A couple of examples are given below.
\startbuffer
\setupthinrules[n=3,inbetween=,color=gray]
test test \thinrules\ test test \par
test test \thinrules [color=green] test test \par
test test \thinrules [height=max, depth=max] test test \par
\setupthinrules[height=.9,depth=.9]
test test \thinrules\ test test \par
test test \thinrules [alternativevariant=b] test test \par
test test \thinrules [alternativevariant=c] test test \par
test test \thinrules [alternativevariant=c,inbetween=\vskip2ex] test test
\par
\stopbuffer
\typebuffer {\getbuffer}
There are a couple of alternative ways to visualize rules
using backgrounds. At first sight these may look strange,
but they make sense in educational settings. The
alternatives are more or less compatible with the more
advanced \METAPOST\ based implementation.
\startbuffer[a]
\setupthinrules
[n=2,
backgroundcolor=gray ,
rulethickness=1pt,
colorkleur=donkerblauw,
after=\blank,
before=\blank]
\stopbuffer
\typebuffer[a]
\startbuffer[b]
\thinrules[alternativevariant=a]
\thinrules[alternativevariant=b]
\thinrules[alternativevariant=c]
\stopbuffer
\typebuffer[b] \getbuffer[a,b]
\startbuffer[b]
\thinrules[alternativevariant=a,background=color]
\thinrules[alternativevariant=b,background=color]
\thinrules[alternativevariant=c,background=color]
\stopbuffer
\typebuffer[b] \getbuffer[a,b]
\startbuffer[b]
\thinrules[alternativevariant=a,height=.8,depth=.8,background=color]
\thinrules[alternativevariant=b,height=.8,depth=.8,background=color]
\thinrules[alternativevariant=c,height=.8,depth=.8,background=color]
\stopbuffer
\typebuffer[b] \getbuffer[a,b]
\stoptext

That is what I want. I have now defined the following much simpler
macro:
\def\GetComment[#1]{
\blank
#1\par
\thinrules[n=4]
\blank
}
and I call it with:
\GetComment[What was the most useful for you?]
