Illegal screens?

[Layman]

Greetings all,

This is my first post here, so please go easy on me

I'd like to hear some informed opinions on a couple of screens that were set late in the Tennessee-Texas women's game on Sunday. Both screens were set by Mercedes Russell, #21 in Orange. Neither one was called by the game officials.

The first was a rather unusual situation because it involves a collision in the backcourt where the screener is not squared to the defender. The second one is a rather typical high ball screen situation. I look forward to hearing your thoughts and insights.
