1. When the empty lines are inserted at a line break they are kept with 
\emptylines but when you use \blank the glue disappears at the begin of 
the page.

2. When you use \blank to insert empty lines before (or after) another 
environment which uses \blank to insert vertical space only the larger 
value is used.
