I understand why you might think this, but this isn't the bad type of loan, and I hope you would trust I would say if I thought it was.
Man City have a revolving credit facility with HSBC for this exact reason - access to ready cash. Allows the club to operate with minimal cash to hand, and make decisions without having to allocate funding ahead of time. For example, the club may well think the success of the first few months might warrant a bigger lump sum of spending on players, or marketing, or various other things that cost lots of money. This kind of facility means they just work out the maths and spend what they think is right. The other way means they'd have to try to budget monthly to 'save up' to spend it - if they even could, given the way PL payments are made.
All entirely normal and nothing to worry about, especially with these owners. My opposition to stuff like this in the past was because we had owners who were manipulating it to fill a financial black hole for themselves, not the club.
