The manual for the function `set-frame-position' says this:

"Negative parameter values position the right edge of the outer
frame by -X pixels left from the right edge of the screen (or the
parent frame's native rectangle) and the bottom edge by - Y pixels
up from the bottom edge of the screen (or the parent frame's native
rectangle)."

Tested with NS port Emacs 28.2 and 29.0.50 on macOS 12.6.

In Emacs 28, when using `set-frame-position' to set the position of
the child frame, when X or Y is a negative value, it correctly sets
the position of the child frame so that its right edge is X pixels
away from the right edge of its parent frame or its bottom edge is
Y pixels away from the bottom edge of its parent frame.

But in Emacs 29, when X or Y is negative, `set-frame-position` sets
the position of child frame's (0, 0) point -X pixels left or -Y pixels
up from its parent frame's (0, 0) point.

`set-frame-position' has inconsistent behavior in Emacs 28 and 29.
