Not necessarily. This is an excerpt from man 2 swapon:

Swap  pages  are  allocated  from areas in priority order,
highest priority first.  For areas with different  priori-
ties,  a  higher-priority area is exhausted before using a
lower-priority area.  If two or more areas have  the  same
priority,  and it is the highest priority available, pages
are allocated on a round-robin basis between them.
