I just tested it - the functionality is the same as cleanse and tenacity. It will only ignore attack speed slows that are combined with movement speed slows. Standalone attack speed slows are not ignored, such as Malphite.

Warning to players going against Master Yi:
 * Recommended: and
 * Discretionary:

Because Randuin's also reduces movement speed, Master Yi's Highlander will counter Randuin's Omen. However, the health may still be useful.
