WolframAlpha[] give results but not parse!

In Mathematica 8.0, the following gives the expected explicit
solution, graphs, etc.:

  WolframAlpha["solve dy/dt=2y(1-y)"]

It even tells me the interpretation as "solve y'(t)=2y(1-y)".  Of
course, just using input 

  =solve dy/dt=2y(1-y)

gives the same results.

However, the following (as well as the Ctrl= input form for it) gives
no Mathematica translation of the input:

  WolframAlpha["solve dy/dt=2y(y-1)","MathematicaParse"]

It is surprising that WolframAlpha "understands" what I asked but
cannot actually tell me in Mathematica syntax the same thing!

Or am I missing something?
