> low pitch vs high pitch vowels where a,ı,o,u are low pitch and e,i,ö,ü are high pitch.

Does that reflect the Turkish terminology? Ordinarily you would call o and u "high" while a and e are "low". The distinction between o/u and ö/ü is the other dimension: o/u are "back" while ö/ü are "front".

> Does that reflect the Turkish terminology?

Yes. The Turkish terms are "kalın ünlü" and "ince ünlü". They literally translate to "low pitch wovel"/"high pitch wovel" )(or "thick wovel"/"thin wovel") in this context.

There is a second wovel harmony rule [1] (called lesser wovel harmony) that makes the distinction you pointed out. Letters a/e/ı/i are called flat wovels, and o/ö/u/ü are called round wovels.
