Between $draw->pathStart() and $draw->pathFinish() you would need to start with $draw->pathMoveToAbsolute(x, y) to initialise the position. All the subsequent calls to "path functions" (including absolute ones) will continue the path.
I would expect pathStart to accept the starting coordinates, and it took me a while to realise that there you need to initialise with a different function.

ImagickDraw::pathStart — Declares the start of a path drawing list
설명
bool ImagickDraw::pathStart
( void
)
Warning
이 함수는 현재 문서화 되어있지 않습니다; 인수 목록만을 제공합니다.
Declares the start of a path drawing list which is terminated by a matching DrawPathFinish() command. All other DrawPath commands must be enclosed between a and a DrawPathFinish() command. This is because path drawing commands are subordinate commands and they do not function by themselves.

Example #1 ImagickDraw::pathStart()
<?php
function pathStart($strokeColor, $fillColor, $backgroundColor) {
$draw = new \ImagickDraw();
$draw->setStrokeOpacity(1);
$draw->setStrokeColor($strokeColor);
$draw->setFillColor($fillColor);
$draw->setStrokeWidth(2);
$draw->setFontSize(72);
$draw->pathStart();
$draw->pathMoveToAbsolute(50, 50);
$draw->pathLineToAbsolute(100, 50);
$draw->pathLineToRelative(0, 50);
$draw->pathLineToHorizontalRelative(-50);
$draw->pathFinish();
$draw->pathStart();
$draw->pathMoveToAbsolute(50, 50);
$draw->pathMoveToRelative(300, 0);
$draw->pathLineToRelative(50, 0);
$draw->pathLineToVerticalRelative(50);
$draw->pathLineToHorizontalAbsolute(350);
$draw->pathclose();
$draw->pathFinish();
$draw->pathStart();
$draw->pathMoveToAbsolute(50, 300);
$draw->pathCurveToAbsolute(50, 300, 100, 200, 300, 300);
$draw->pathLineToVerticalAbsolute(350);
$draw->pathFinish();
$imagick = new \Imagick();
$imagick->newImage(500, 500, $backgroundColor);
$imagick->setImageFormat("png");
$imagick->drawImage($draw);
header("Content-Type: image/png");
echo $imagick->getImageBlob();
}
?>
