When the sample of lead being compared to the sample of water has a greater mass.
The statement makes a comparison between the force of gravity acting on two objects...one lead, the other water.
The force of gravity (weight) is dependent on the mass of the objects. It is entirely possible that the same water have a great mass (and thus have a greater weight and be "heavier") than the sample of Lead.
A more accurate way to phrase the statement would be to relate the densities of each substance,
"Lead is more dense than water",
This statement is accurate for all quantities of Leads and water.

We confuse weight and mass because most of us (my 8th grade science teacher aside) deal with life on earth. In order for that statement to be true you have to make two assumptions. The lead and the water are being "weighed" in the same gravitational field.
The volume of lead is equal to the volume of water being weighed. (The volume of lead could be less than the that of the water to a certain extent and the statement would still be true but I think that it outside of gist of this question.)

When the piece of lead you are dealing with is heavier than the amount of water you have.
