Many seeming oddities in the language are merely conventions established 
by the HyperCard team.  IIRC the need to lock the cursor to have it 
maintained after idle is one of them (though personally it makes sense 
to me; seems more convenient than needing to explicitly unlock).

In this case it seems the LC team tried to document it - from the 
Dictionary entry for "cursor":

     If the lockCursor property is set to false, LiveCode automatically
     sets the cursor according to its location once the handler finishes.
     (For example, the cursor normally turns into an arrow over a menu,
     an I-beam over an editable text field, and so on.) To retain the
     cursor property after a handler finishes, use the lock cursor 
command.
