I believe it would count because there is no exception listed.
The key part off the government's website:
If you hold a Working Holiday visa, the main purpose of your visit
must be for an extended holiday. You can do any kind of work over the
course of your 12 month stay in Australia, however all Working Holiday
visa holders are limited to a maximum period of six months work with
any one employer. This limitation applies to all employers and all
forms of work.
If you're still actively engaged in work for your existing employer, it would not be a holiday as such. You could also fall afoul of the six month limitation on single employers. The employment (max of six months with one employer) and study limitations (max four months) are designed to ensure that people have the correct form of visa.
Given your description of the situation, if you intend to continue working for your current employer a 12 month Visitor visa would be more appropriate as it does not enforce limitations on your employment.
