What you don't see is that Windows' echo added a CR so you get to see
the second line followed by CR-LF and the rest of the (overwritten)
first line.

You can delete the CR and get the correct output, for instance using:

cmd /c echo UVWXYZ | tr -d "\r" >> foo.txt

Or directly with something like:

cmd /c echo UVWXYZ | tr -d "\r" | od -t x1z

take out the translate part to see the CR-LF.
