I have seen developers confused by the words writing instructions before, suggesting either they do not know what writing is, what instructions are, or that they cannot differentiate between writing an application and writing a few instructions.

Not OP, but I infer that "writing instructions" equates to a lot of basic scripting - change the colour of that button, show a calendar, trigger that animation, send data to the validation script and display an X or a tick depending. As differentiated from, or opposed to, writing complex applications that require thought, design and awareness of best practice.
