Your syn match command either needs a contains=hl1, or your syn region
command needs a containedin=potltab0.

Your syn match will match "a space at the beginning of the line,
followed by anything not a tab, followed by any number of anything".
This means that on lines where (test) is not at the very beginning of
the line, the match will apply first, taking precedence. Syntax rules
do not allow matches of other rules within them unless you tell them
to.

With your two sytax rules I get the 2nd line to match your region, but
not the first:

...(test)
(test)

If I add a containedin=potlTab0 to the syn region, the (test) on both
lines is highlighted.
