Why this code does not work as expected when changing the limit of loop?
Consider the following code
documentclass{minimal}
usepackage{tikz}
usetikzlibrary{calc}
begin{document}
pagestyle{empty}
pgfdeclarelayer{background}
pgfsetlayers{background,main}
xdefinecolor{darkgreen}{RGB}{175, 193, 36}
newcounter{cntShader}
newcounter{cntRoot}
setcounter{cntShader}{20}
colorlet{helixcolor}{darkgreen}
begin{tikzpicture}
foreach y in {86,38,15}{
setcounter{cntShader}{1}
coordinate (a) at (0,0);
coordinate (b) at (0:1);
foreach x in {1,...,y}{
coordinate (c) at ($ (b)!1cm!270:(a) $);
begin{pgfonlayer}{background}
draw[fill=helixcolor!thecntShader] (a)--(b)--(c)--cycle;
end{pgfonlayer}
setcounter{cntRoot}{x}
addtocounter{cntRoot}{1}
node[fill=white,draw,circle,inner sep=1pt] at (c)
{$sqrt{thecntRoot}$};
coordinate (b) at (c);
addtocounter{cntShader}{2}
}
}
node[fill=white,draw,circle,inner sep=1pt] at (0:1) {$sqrt{1}$};
end{tikzpicture}
end{document}
Particularly this line foreach y in {86,38,15}{
Here says that there are 3 loops
x from 1 to 86, x from 1 to 38 and x from 1 to 15.
If one removes 38 and 15 yields foreach y in {86}{
And the code is executed in strange way because it skipt this particular part (a)--(b)--(c)--cycle;
Why?
Why does the triangles are not formed? (Following the code, there is a first triangle with vertex (a),(b),(c), namely 
, then the next triangle with vertex $(0,0),sqrt{2},sqrt{3}$, etc. )
Could you please explain?
Thank you in advance.

The code does work in the sense that there is no error. Obviously faces of the inner parts of the spiral do not get drawn if you doforeach y in {86}.
