ConTeXt: Is ist possible to use matrices nested like in 'block' matrices?

I tried to use context's startmatrix/stopmatrix nested with predefined matrix blocks. In latex it works like this:

documentclass{article}

usepackage{amsmath}



defmatOne{begin{matrix}1 & 0 \ 0 & 1end{matrix}}

defmatTwo{begin{matrix}a\bend{matrix}}

defmatThree{begin{matrix}c & dend{matrix}}



begin{document}

    begin{align*}

        begin{pmatrix}

            matOne & matTwo\

            matThree & e\

        end{pmatrix}\

        begin{pmatrix}

            1 & 0 & a\

            0 & 1 & b\

            c & d & e\

        end{pmatrix}

    end{align*}

end{document}

The top matrix out of blocks looks the same as the bottom one. In context I tried the following:

definemathmatrix[pmatrix][left={left(}, right={right)}, distance=1em]



defmatOne{startmatrixNC 1 NC 0 NRNC 0 NC 1NRstopmatrix}

defmatTwo{startmatrixNC aNRNC bNRstopmatrix}

defmatThree{startmatrixNC c NC dNRstopmatrix}

Here the top matrix looks different than the bottom one. It seems that the distance isn't applied after a block matrix. Is there a way to fix this?

I'm unsure whether this breaks something else but it seems as if the definition of NC is not reverted properly. Reported here: https://mailman.ntg.nl/pipermail/ntg-context/2017/089631.html

I cranked distance up to 2em to make the difference more visible.

Thanks Henry, so it seems like this is a bug in context. Your fix works in this case, but if a add a fourth column with another mathTwo in the first row and an f in the second it doesn't work anymore. If you keep adding some columns it adds the distance only every second column.

FWIW, nested matrices work currently with the current version of ConTeXt (2019.03.21). The bug was fixed with this commit. The code listed in the example gives the following:
