Is G1 sufficient techbnique forSC 2.4.1?

Hello WG,

SC 2.4.1 sufficient techniques:
The doc states any one of techniques G1, G123, G124 are sufficient.
Assume: 
No structural markup techniques (H50, H69, H70, H64 is used.  
the page has top nav links (repetitive) and left nav links and one main content and footer section.
The links in the left nav are several and are repetitive  within section of top nav links.
Issue:
Does the website comply with SC 2.4.1 if only G1 is implemented? 
How can a screen-reader user skip the top nav links and go to left nav links?
How will a user make out where top nav links end and left nav begin? 

Comment:
G1 is alright if page has no left or right side content but just top nav and header section, a main content and footer section.
Maybe other methods like G123, G124 are more useful here.

There should be a skip top-nav link with target set at start of left nav and a skip to main content positioned at start of left nav on such pages.
A lesspreferred method is to have both skip links at page start.  
So please consider if G1, G123, G124 are  substitutes for one another.

Also should every skip-nav technique require that the  link becomes visible as soon as it gets tab focus so that sighted keyboard-users can benefit from them?It mainly helps this group of users. AT-users often rely on  heading and list markup on pages that are properly marked up.
