Thank you for bringing this most misinterpreted quote for the debate.
a- Did Marx undervalued the task of "seeking to understand the world"?
No, he apparently did not, since he has spent most of his life "understanding" rather than "changing". Of course it is arguable that his studies and writings were the essential tools to "change" or revolutionise the existing class structure. This changing bit comes after understanding [particularly for a philosopher].
b- What did Marx mean with "The point, however, is to change it."?
My understanding is that, he is drawing attention to the urgent task of changing the established order of the day. He was probably not naive thinking that this task could have been achieved by philosophers alone, therefore he was addressing to the masses.
c- Unfortunately, Marx's quotation was used as a demagogic instrument [as if by saying - we do not have the luxury of "understanding" now, let us change it first we will understand it later] to keep the masses ignorant by politicians supposedly defending Marx's ideas.
