Does this question account for areas where X is positive and Y is negative? For example, in the fourth quadrant, aren't all X values greater than Y values? Wouldn't the same apply for half of the third quadrant as well?

No, the question statement implies Quadrant 1 only.

... , what is the probability that x > y > 0?



If we didn't have that "> 0", then your reasoning would be true, we would need to look into all quadrants.

Sometimes a little part of the information in a question statement slips the mind and it can affect the whole reasoning and lead to a wrong answer choice. Reading every word and symbol in a question statement is very important. Do not hurry, when reading the question statement.
