True, the problem is when the wrong solution appears to work in a
particular situation.

Without testing, I'm pretty sure that

1 setlinecap
0 0 moveto 0 1 lineto stroke
0 1 moveto 1 1 lineto stroke
1 1 moveto 1 0 lineto stroke
1 0 moveto 0 0 lineto stroke

would produce the same result as

1 setlinejoin
0 0 1 1 rectstroke

and

2 setlinecap
0 0 moveto 0 1 lineto stroke
0 1 moveto 1 1 lineto stroke
1 1 moveto 1 0 lineto stroke
1 0 moveto 0 0 lineto stroke

would produce the same result as

0 setlinejoin
0 0 1 1 rectstroke

Easy for beginners to get tricked sometimes.
Hope this helps.
