They used to make us build recursive descent compilers in computer
science. That's where I learned to express myself in a way that
wouldn't cause type errors. Confusing a noun with an adjective will
cause a type error. And, also outside of the computer science field,
confusing their denotations, object and properties, respectively, with
each other leads to wrong conclusions.
So, with your permission, I will restate what you just wrote; object
if I misrepresent you:

Not all verb forms in PIE based on the aorist stem are preterites .
And the aorist stem imparts perfective aspect to the forms based on it
rather than some tense.
