Yes, that was the intention. We will rephrase it to say

   [...] The EST-coaps client MUST support
   Block1 only if it sends large EST-coaps requests that would 
   otherwise result to IP layer fragmentation.

Section 5.6:

The EST-coaps client MUST support
   Block1 only if it sends EST-coaps requests with an IP packet size
   that exceeds the Path MTU.

I think the requirement for when Block1 is required to be supported in the 
above sentence is unclear. Is the intention to say: An EST-coaps MUST support
block1 to be capable to send requests that would otherwise result in the 
reliance on IP level fragmentation?
