After spending 4 years 7 months in UK on ICT Tier 2 Staff dependent visa, I have recently moved to Tier 1 Entrepreneur visa as main applicant on £200K route

Hereby, I am having few questions on which I am looking expert advice as Page number 15 of The Points Based System (Dependant) - Policy Guidance version 01/2019 document says as below
"
Family members of Tier 1 (General), Tier 1 (Entrepreneur) and Tier 1 (Post Study Work) migrants
70. If the Tier 1 Migrant is outside the United Kingdom or has been present in the United Kingdom for less than 12 months, you must show that you, the Tier 1 Migrant, or (for children) your other parent have at least £1890 to support you; this is in addition to any funds the Tier 1 Migrant needs to prove they have enough money to support themselves.
71. If the Tier 1 Migrant has been in the United Kingdom for 12 months or more, you must have £630 to support yourself.
72. For example, the Tier 1 Migrant has been in the UK for 6 months and is making an application at the same time as their spouse and two children. They must show that they have £1890 for their spouse and a further £1890 for each child, in addition to £945 required for their own support. In total the family will require evidence that they hold £6615 in available funds (£1890 x 3 = £5670+£945).
73. If the same Tier 1 Migrant and their family had been present in the UK for two years, they would require evidence that they held £2835 (£630 x 3 = £1890 + £945) in available funds.
74. If you are applying as the family member of a Tier 1 (Entrepreneur) migrant you cannot use the same funds to meet the maintenance requirement that the Tier 1 (Entrepreneur) used to meet the attributes requirement (appendix A of the Immigration Rules).
