I am saying that you don't know how strong or fragile your blood vessels may be until your BP goes "too high".
Too high for you may be a significantly lower level than too high for me. One person may stroke at a systolic of 180, another person may be fine at 200.
Cholesterol helps keep your blood vessels healthy (among other things). Healthy means strong and flexible. If your body doesn't have enough cholesterol to keep your blod vessels healthy that could lower your threshold.
I tend to run rather low BP. I've been as low as 70/systolic with no signs of any problems (but the docs freaked!). I rarely go over or even into the 130s. Now, if you checked my BP while I was agitated, it would likely be significantly higher....maybe too high for some.
It's the combination of the 2. Higher BP with healthy blood vessels isn't as dangerous as the same BP with weak, fragile blood vessels. If you keep your BP low enough you're unlikely to have a stroke, regarless of your vessel strength. But again, "low enough" could be too low for you to function.
Look at people that have a arterio-venous malformation. (AVM). When these are discovered, usually in a "leaking" state, the number one thing they try to do is lower the blood pressure. They know that these vessels are more fragile and higher BP is more likely to cause a rupture before they can get in and repair it.
Unfortunately few of us (if any) can tell how fragile or strong our blood vessels are. But since cholesterol is a main ingredient in the structure of blood vessels, it makes sense that blood vessel structure would suffer when cholesterol levels are low.
