I'm a new player

Can two turns be concurrent?

For example, in this game: http://www.conquerclub.com/game.php?game=7813445
there are these moves:
2010-10-18 11:54:17 - tozzo received 3 troops for 8 regions
2010-10-18 11:54:38 - tozzo deployed 3 troops on Vancouver
2010-10-18 11:54:38 - MrDweeb received 5 troops for holding Europe
2010-10-18 11:54:38 - MrDweeb received 3 troops for 10 regions
2010-10-18 11:54:43 - tozzo assaulted Anchorage from Vancouver and conquered it from mrcomp_ca
2010-10-18 11:54:44 - MrDweeb deployed 8 troops on Lagos
[...]
2010-10-18 11:56:08 - MrDweeb assaulted Cairo from Istanbul and conquered it from mrcomp_ca
2010-10-18 11:56:44 - tozzo reinforced Los Angeles with 1 troops from Mexico City
2010-10-18 11:56:44 - tozzo ended the turn and got spoils
2010-10-18 11:56:45 - MrDweeb reinforced Nairobi with 4 troops from Cape Town
2010-10-18 11:56:45 - MrDweeb ended the turn and got spoils
Is it normal?

Thanks a lot.
