yes, the location of each installed bundle should be unique
- see the core spec, section 4.3.3 page 82 - and that if you
try to install a bundle with an existing location then you will
get back the already installed bundle for that location.
however, note the reference to bundle validity:
"A bundle must be valid before it is installed, otherwise
the install must fail. The validity of a bundle is discussed
in Bundle Validity on page 64."
and one of the validity errors listed on page 64 is:
"Installing a bundle that has the same symbolic
name and version as an already installed bundle."
otherwise you would end up with the same bundle installed
in two locations, hence these additional validity checks
