Starting with 0.00 in display, I type:

[-] [2] [shift] [Y^X] [2] [=] yields 4

whereas [-] [2] [x^2] [=] yields -4

Are you using chain mode? [Y^X] is an operator with two arguments and thus completes the pending operation [-] before being executed. [x^2] just squares what is in the display, 2 actually, and the [-] operation is carried out with the result of this operation.
