power steering fluid flush - how bad did i screw up?

Hi all,
95 GT
power steering fluid was low and has never been changed, car has 140k miles on it.

seems i needed to use mercon automatic trans fluid for the power steering. i thought i was doing ok when i used castrol transmax mercon V. It says on the front it's good for ford and it exceeds mercon requirements. back says (in yellow below) that its good for power steering. i guess i had stopped reading there and didnt notice the next sentence that says do not use in applications calling for mercon sp, mercon lv, or Type F'.
that last sentence has me worried. i cant tell if they are saying dont use it as transmission fluid if you need type F, or dont use it as power steering fluid if you need type f, or dont use it for anything thart needs type f?

so, assuming this isnt the right stuff, how bad is this that i already flushed the system with this? do i go buy the right stuff and flush it again and all is well? or am really screwed?

thanks

so i finished up the flush, did the turning the steering wheel, etc.
started the car and immediately noticed squealing when I turned the wheel. I am pretty sure the noise wasn't there previously.
i drove the car for about 15 minutes. seems the noise wasnt as loud by the end of the 15 minutes when i got back in the driveway.
it isnt a persistent squealing. it only happens when i turn the wheel. i was under the impression that if there was any whining due to incorrect fluid or a pump problem, it would be a consistent whine, is that accurate?

also, when the car front end was jacked up i moved the tire a bit (a tiny tiny bit) with my hand and the noise seemed to be coming from the tire area rather than the pump or rack area, does that make sense? it sounded a lot like sound the metal rotor shield makes when you move it a little, but that shield isnt touching the tire or anything.

i will be looking around at things again today, but i am trying to understand what may be going on.

also, do i care about this noise if it is actually the famous ford whining?

thanks
