Looking at the diagram below, the rectangle is the extents of the glyph.
In this example think of something like a 'g' where most of it is above
the origin but a bit is below. In cairo the positive Y axis is down. The
y bearing is the distance from the origin to the top of the extents. In
this example the y bearing is negative as the top of the extents is on
the negative Y side of the origin.
