I don't see any difference.  Maybe I'm misunderstanding what you mean.

Whitespace between adjacent encoded words have to be ignored according
to RFC 2047:

,----[ rfc2047.txt ]
|    (=?ISO-8859-1?Q?a?= =?ISO-8859-1?Q?b?=)     (ab)
| 
|            White space between adjacent 'encoded-word's is not
|            displayed.
| 
|    (=?ISO-8859-1?Q?a?=  =?ISO-8859-1?Q?b?=)    (ab)
| 
|         Even multiple SPACEs between 'encoded-word's are ignored
|         for the purpose of display.
| 
|    (=?ISO-8859-1?Q?a?=                         (ab)
|        =?ISO-8859-1?Q?b?=)
| 
|            Any amount of linear-space-white between 'encoded-word's,
|            even if it includes a CRLF followed by one or more SPACEs,
|            is ignored for the purposes of display.
