Two cascaded T-type flip-flops will count in the normal binary sequence:
0 - 1 - 2 - 3 - 0
i.e.
00 - 01 - 10 - 11 - 00

You are asking for:
00 - 10 - 01 - 11 - 00

What can you observe about the difference between these two sequences?

I think it's a matter of sloppy work.

If you assume that the first flip flop is the most significant bit and the second is the least significant, then it counts in the desired 0-2-1-3 sequence. If you assume the first flip flop is the least significant bit, which would be more typical, it counts 0-1-2-3.
