not really

not internally, but the typical usage is another:
1. for L somewhere is a TS-Condition.
each (combination of) TS-Condition means an extra cache-variant, so a 
page is cached for each identified occurence of L

2. in these caches the L is consistent always the same (it is the one 
the condition identifies)

3. on pages without a matching TS-Config, any value of L is cached in 
all links. This is the reason for strange occurences of L=http://.... 
(google for 'typo3 straneg l parameter' and you will find multiple 
requests.) they are injected and cached. cached until google indexed 
them and they never will be removed.

in the same way will be the std-cache (no condition about the additional 
param) be injected with any value of this additional parameter if you 
include the param in linkVars without individual Cache by TS-condition
