That doesn't provide any information about whether or not the food should or should not be in the oven during the heating up period.
It doesn't have to. Since the "preheat" instruction is invariably the FIRST step, that in itself should tell you it should be done before the food is put in (or even prepared). Whether you say "heat" or "preheat" is irrelevant when it's the first step.
Additionally, if you put the food in
during the heating up period, you haven't
heated the oven, you have simply set the temperature and turned it on. If the instructions say to "heat oven to 350 degrees" then it wouldn't make sense to put the food in before it gets to that temperature, since it hasn't actually been heated to 350 degrees yet.
The only time the word "preheat" makes sense is if for some strange reason you should heat the oven to some temperature, and then change the temperature once the food is in the oven. Even then it isn't necessary.
