You only look at the cast time as a number, not on the percentages.
So, let's try...
With both, BL and EM active, you'll have a 1sec LB. EM will last 15sec, so you'll do 15 LBs while both are active and 21.74 LBs for the remaining duration of BL only. Now we have to add the LBs casted in additional 15sec, so we can match the 55sec of seperated BL and EM, which would equal to 10 LBs.
So with stacked EM and BL, you'll have casted 46.74 LBs.
Now if we seperate them, then you'll have 40sec BL and then 15sec EM.
In the 40sec of BL, you'll cast 34.78 LBs, while in the 15sec of EM, you'll cast 11.54 LBs.
This adds up to 46.32 LBs.
What this shows is, that the difference between stacking haste and not seperating it is in that case rather low, but there is one, which shows that stacking is slightly better.
