Mythic Eldritch Heritage

[Just Big Boned]

Am I reading this right, that, essentially:

Eldritch Heritage + Mythic Eldritch Heritage

is the same as

Eldritch Heritage + Improved Eldritch Heritage + Greater Eldritch Heritage

except:

your sorcerer level never catches up to your class level (a la Greater EH) except when it concerns your 1st level power which catches up immediately. Also, you get the full compliment of powers rather than having to pick and choose between them.

Is that right?

Yep.

Also, you don't need more than 13 Cha to get the bloodline powers (vs. 15 Cha for Improved and 17 Cha with Greater).
