Sadly, I don't think it does. If the largest value happens to be 
duplicated in different rows and columns, the formula generates the 
address of neither but instead that of the intersection of that row 
and that column. Try changing either B1 or A2 to 7: for such separate 
changes the formula works. But now change both B1 and A2 to 7: the 
formula generates neither B1 nor A2 but B2 - which is not either of 
the cells containing the equal largest values.

It's Boolean expression, giving the result TRUE or FALSE. It's 
testing the individual cells in the range A1:C2 to determine whether 
they are equal to the maximum value of that range. It may seem 
strange to be able to write such an expression for an entire range 
instead of for individual cells, but that is the power of array formulae.
