No, they are intelligent enough to know they (potentially) still have all of the CPUs available. The other containers are not implicitly capped.

My question relates to a T2000 which is 8core. I want to restrict one zone to use only a single core while the other remain unrestricted, Would the other zone still think they've got 8core available to them though?
Sure, they'll have the CPUs available (more precisely all zones will still share all of the CPUs).
By the way, if you want to cap the container to one core on a T2000, make sure you set ncpu to 8, not 1.

vzsplit

vzsplit(8)							    Containers								vzsplit(8)

NAME

       vzsplit - generate a sample container configuration file

SYNOPSIS

       vzsplit [-n numve] [-f conf_name] [-s swapsize] [-v yes|no]

DESCRIPTION

       The vzsplit utility is used to split the Hardware Node into equal parts.  It generates a full set of system resource control parameters for
       the given number of containers. The values are calculated from the total physical memory of the Hardware Node the utility runs on, and  the
       number of containers the Hardware Node shall be able to run even if the given number of containers consume all the resources available.

       Without	any  option  given,  vzsplit prompts for the desired number of containers and outputs the resulting resource control parameters to
       stdout.

       If there are not enough system resources to run the specified number of containers, an appropriate message is shown and the sample configu-
       ration file is not generated.

OPTIONS

       -n numve
	      Specify the number of containers.

       -f conf_name
	      Specify  the  configuration  sample  name  to  write  configuration  to,	instead of standard output. The file created will be named
	      /etc/vz/conf/ve-conf_name.conf-sample.

       -s swapsize
	      Specify the swap size in Kbytes. If this option is not given, the swap size is read from /proc/meminfo.

       -v yes|no
	      Whether to generate VSwap enabled configuration. Default is auto-detect by checking if running kernel is VSwap capable; this  option
	      overrides auto-detection.

EXIT STATUS

       vzsplit returns 0 upon a successful execution. If anything goes wrong, it returns 1.
